No. 64 July 2002

Official Newsletter of the International Association for Mathematical Geology

tarting with this issue, the Newsletter will not be mailed to all IAMG members anymore. Only a small group (about 20 %) of the addressees marked the checkbox on their membership renewal form to indicate that they preferred to still receive a hardcopy of the Newsletter via the postal service. From now on the memberFrom the Editor From the Editor ship will be alerted by From the Editor e-mail when the Newsletter is uploaded to the IAMG website (www.iamg.org). It is available there in PDF format and can be either read onscreen or downloaded and printed. By the way, the last eight Newsletters, back to number 56, are also available for viewing or download from the website. This change is part of the streamlining of the IAMG affairs. See the President’s Forum (p. 3) for more on the recent changes. The new IAMG office will also handle the distribution of the Newsletter (both the e-mailing and the mailing) and should be notified when your e-mail address or postal address changes. This new arrangement will save the Association money with reduced printing, handling and mailing costs and will make the Newsletter available in a more timely fashion. Let us know if you agree or if you have suggestions for improvement of the service. On another matter: your Newsletter editor keeps moving. After a stint of almost two years as a guest scientist with the Kansas Geological Survey at the University of Kansas in Lawrence, he has opened his new office as “consulting geologist” in Dallas, Texas. This completes the circle back to where he started out almost 40 years ago when he joined Arco Oil & Gas (then Atlantic Refining) in their research department. The company is gone and the city has changed and grown but many old friends are still here to share the memories of the early years. The time in Kansas was a wonderful experience both in terms of interesting research and interactions with great people and being able to get much background on the history of the IAMG, by having access to several of the founders and leaders of the Association. We hope fervently that the Math Geology Group there will find a new home or will manage to reverse their ill fortunes in the near future. Harald S. Poelchau


Call for Proposals to Organize the

IAMG2005 Conference

IAMG2003 Annual Conference in Portsmouth

The Annual Conference in 2003 is to be held in Portsmouth, UK from Sunday 7 September to Friday 12 September, hosted by the School of Earth and Environmental Sciences, University of Portsmouth. In IAMG2003 we wish to highlight the analysis, modelling and simulation of geological hazards whilst also providing a programme of symposia of sufficient breadth to attract state-of-the-art contributions from across the full range of mathematical geology. Across the world, activity and funding in the field of geological hazards has increased dramatically in recent years. We believe it timely that an international conference should highlight the ubiquitous r?le played by mathematical geology in the effective identification, remediation and management of geological hazards. Contributions, both oral and poster, are invited for symposia under the following headings Predictive Modelling of Geohazards I - Volcanic hazards Written proposals for 2002 funding, which must be received no Predictive Modelling of Geohazards II - Glacial hazards later than close of business on August15, 2002, should be submitPredictive Modelling of Geohazards III - Geotechnics ted to: Predictive Modelling of Geohazards IV - Earthquakes and seismicity Donna Dennison Predictive Modelling of Geohazards V - Landslide hazards Student Grants Committee, IAMG Office Stochastic Modelling I 4 Cataraqui St., Suite 310 Stochastic Modelling II - Geotechnics Kingston, ON K7K 1Z7 Canada Geoscience Information Systems e-mail: office@iamg.org

John Davis to be Distinguished Lecturer
The IAMG Distinguished Lecture Series committee has proposed Dr. John C. Davis of the Kansas Geological Survey as the IAMG's Distinguished Lecturer for 2002-2003. Dr. Davis was nominated in response to the "Call for Nominations" issued to the IAMG membership in the last newsletter and his nomination was unanimously endorsed by the DL committee. As an internationally recognized scientist, experienced public speaker and dedicated teacher, John Davis easily meets the qualifications for a distinguished lecturer established in recommendation #3 of the 2000 Report of the Lecture Series Commission. He has also accepted to perform the duties of a distinguished lecturer established in recommendation #8 of the same report. Upon formal award of the lectureship and his acceptance thereof, the DL committee will work with Dr. Davis to select host institutions and itineraries as financial resources permit. Heinz Burger, organizer of the 2002 IAMG annual meeting, has been asked to allocate 15 minutes or so of the schedule for the announcement of the Distinguished Lecturer and the titles of his selected talks. This will provide visibility to the Lecture Series and an opportunity for potential hosts that are attending the meeting to approach the Lecturer. The next step for the committee will be to work with the speaker in selecting host institutions and planning an itinerary. If you have suggestions for the committee about institutions who would like to invite the Distinguished Lecturer, please contact Alec at desbarat@NRCan.gc.ca. Alec Desbarats and his and his Committee are to be congratulated for an excellent choice. <>

2002 Krumbein Medal and Griffiths Award
The Awards Committee, consisting of John Cubitt, John C. Davis, André Journel, Hugh Rollinson, IAMG president Graeme Bonham-Carter (non-voting) and chair Vera Pawlowsky-Glahn, has completed selection of award recipients for 2002, who are 2002 Krumbein Medal: Michael Ed. Hohn, USA 2002 Griffiths Award: Ian Lerche, USA M.E. Hohn was elected from a field of five candidates, I. Lerche had three opponents. Following the By-Laws and guidelines of our Association, evaluation of all nominees was based on resumes and accompanying statements distributed electronically among all members of the Committee. I am happy to say that this time no problems appeared with attached files; a definitive breakthrough in the dynamics of the awards committee. For the Krumbein Medal there are three criteria, which can be summarized as follows: A. Distinction in application of mathematics or informatics in the earth sciences; B. Service to IAMG; and C. Support to professions involved in the earth sciences, while for the Griffiths awards we have only two: 1. Outstanding teaching in general and 2. Teaching that involves application of mathematics. All nominees who did not make it in this round will be automatically considered for the next selection, but fresh nominations are welcome. Please look at the front page “Call for Nominations” for 2003. If you do not nominate your favorite geomathematicians, they will never receive the recognition they deserve. I would like to thank the following persons for their active support to the Awards Committee during the 2002 selection process, either as submitters of nominations and/or writers of laudations. It makes the work much more pleasant and, without their effort, our task would be impossible: Heinz Burger, Tim Cross, Roussos Dimitrakopoulos, Carol A. Gotway Crawford, Richard McCammon, Ricardo A. Olea, Tetsuya Shoji. The list is certainly not very long, and I would like to encourage our rank-and-file to a more active participation. There is no other way to make our awards and our association more prestigious, and this will benefit all of us. Presentation of the two awards is scheduled to take place in the coming Berlin conference in September 2002. Laudatios of the recipients will appear in the proceedings of the conference and in the Association’s site at the Internet. Furthermore, citation of the Krumbein medalist will be published in Mathematical Geology and of the Griffiths awardee in Computers & Geosciences. And now its time to say good-bye. Heinz Burger was approved by Council as Awards Committee chair for the period 20022006 on Dec 13 2000, so he is taking over the task. I wish him good luck and I thank very warmly everybody in the Association for their support and friendship. Un fuerte abrazo a todos y a todas y ?hasta la vista! Vera Pawlowsky-Glahn, Chair Awards Committee

Mathematical Geology Ends at Kansas Geological Survey
On June 3, 2002, M. Lee Allison, Director of the Kansas Geological Survey, announced that the Mathematical Geology Section of the Kansas Survey was to be disbanded and all staff members of the Section, save one, were to be fired effective June 3, 2003. According to Allison, the firings were necessitated by a budgetary shortfall which resulted from the KGS having its State appropriation cut by about $250,000. Allison stated that the Mathematical Geology Section was chosen for elimination because “it was not central to the mission of the Survey.” The Mathematical Geology Section was founded as the Geologic Research Section in 1962 by Daniel F. Merriam. In 1970, John Davis became Section Chief and has directed the Section ever since. Although the Section’s name has changed several times, it has maintained a focus on quantitative geology and the development of computer software for the earth sciences. Over its 30-year plus history, the Section has gained a worldwide reputation as one of the leading centers of mathematical geology and has been a staunch supporter of the IAMG. The Section was the host for IAMG2001, the last annual meeting held in Cancun, Mexico. Among its other accomplishments, the Kansas group was noted for hosting a succession of Visiting Research Scientists from around the world, including almost all of the leaders in the field. It contributed to the spread of mathematical geology via short courses, training programs, and a policy of welcoming students and professionals from industry and academia. The group also developed widely-used software including programs for contour mapping and geostatistics, petrophysics and log analysis, and more specialized applications. Scientists to be fired include John Davis, author of Statistics and Data Analysis in Geology, 3rd. ed., an IAMG Past President, Krumbein medalist and first IAMG Distinguished Lecturer; John Doveton, first IAMG Griffiths Award recipient and author of the AAPG book, Geologic Log Analysis Using Computer Methods and other books on petrophysics; Ricardo Olea, IAMG Past President and editor of IAMG monograph 3, Geostatistical Glossary and Multilingual Dictionary and author of Geostatistics for Engineers and Earth Scientists; Geoff Bohling, researcher in mathematical modeling of dynamic systems and current IAMG Treasurer; Dave Collins, mineral economist and specialist in GIS applications, and JoAnne DeGraffenreid, IAMG Monograph Editor. Gina Ross, GIS specialist and organizing chairman of IAMG2001, was the only member of the section spared termination. The members of the Section are uncertain about their future plans. Does anyone need a ready-to-go research and development group? <>

IAMG Journal Report
C&G Best Paper Awards 2001
The competition for Best Paper in Computers & Geosciences during 2001 has resulted in a tie for first place. The two winning papers are: “Three-dimensional reconstruction and modelling of complexly folded surfaces using Mathematica” by Ross R. Moore and Scott E. Johnson: C&G 27(4), 401-418, and “STORMSED1.0: hydrodynamics and sediment transport in a 2-D steady-state, wind-and wave-driven, coastal circulation model” by Janette Cookman and Peter B. Flemings: C&G 27(6), 647-674. Ross Moore is an Australian. After a first degree from University of Melbourne, he qualified in 1981 for a DPhil and University of Oxford, after studying Mathematical Physics and Pure Mathematics. He returned to Australia, for a post-doctoral position at the ANU in Canberra, then since 1986 at Macquarie University in Sydney. Ross's main interests are in developing, using and extending computing software for tasks ``useful to mathematicians''. This includes technical typesetting, as well as working with programs for the graphical display of mathematical concepts. He is on the board of directors for the TeX Users Group, and maintains the website for the forthcoming ICIAM 2003 -- the 5th International Congress in Industrial and Applied Mathematics. It was at Macquarie University where Ross first met Scott Johnson; rather, it was Scott who found Ross, when looking for someone to help him with mathematical reconstructions of inclusion trails visible in serial thin-sections. This led to several papers, published in Computers & Geosciences and elsewhere. The prize paper recalls this work, and expands on the idea of using general-purpose mathematical software to help describe and model specific concepts in the geosciences. Scott E. Johnson’s research centers around the spatial and temporal relations among deformation, metamorphism and magmatism at convergent tectonic boundaries. He is particularly interested in microstructures and microstructural processes in igneous and metamorphic rocks formed in these environments. Scott earned his B.Sc. degree in 1985 from the University of New Mexico, Albuquerque, and his Ph.D. degree in 1989 from James Cook University, Australia. He held various research fellowships at James Cook University and Macquarie University in Australia from 1989 to 2000, including a Rothmans Foundation Fellowship and an Australian Research Council Queen Elizabeth II Fellowship. He now holds the Structural Geology position at the University of Maine in Orono. Janette L. (Cookman) Metzger graduated from Michigan Technological University in 1996 with a degree in Geological Engineering and received a Master of Science degree in Geosciences from The Pennsylvania State University (PSU) in 1999. She developed STORMSED1.0 as a M.S. thesis project with Dr. Peter B. Flemings at PSU. She worked as a Geologist in the East Texas Bossier Sand natural gas play at Anadarko Petroleum Corporation in Houston, Texas from 1999-2001, and is currently employed as an Associate Geologist at Brown and Caldwell Environmental Engineers & Consultants in Boston, Massachusetts.

MARMAP System Partnership
Geospatial data form the foundation of an information-based society. Consider a 21st Century digital government scenario of the following nature:? What messages do multicategorical thematic maps and cellular surfaces have about the large landscapes they represent? And at what scale and at what level of detail?...Does the spatial pattern of the map reveal any societal, ecological, environmental condition of the landscape? And therefore can it be an indicator of change?...How do you automate the assessment of the spatial structure and behavior of change to discover critical areas, hot spots, and their corridors?...Is the map accurate? How accurate is it? How do you assess the accuracy of the map? Of the change map over time for change detection? What are the implications of the kind and amount of change and accuracy on what matters, whether climate change, carbon emission, water resources, urban sprawl, biodiversity, indicator species, or early warning? And with what confidence, even with a single map/ change-map? A primary purpose of MARMAP System Partnership is to develop sound methodology and appropriate software for the quantitative analysis and interpretation of multi-categorical maps and cellular surfaces (inferential geospatial informatics) involving landscape pattern analysis, multiscale landcover landuse change detection, accuracy assessment, critical area detection and delineation, disease mapping and geographic surveillance, prioritization and ranking without having to integrate multiple indicators, and a few more.

Conference Reports
Baltic-7 - Kaliningrad
The IAMG co-sponsored the 7th Conference of Baltic Geologists, "Baltic-7", held in Kaliningrad, Russia, on April 21-27, 2002, and organized a technical symposium on "GIS Tools for Mapping Marine Sediments." The Baltic-7 Conference organizer was Prof. Emel Emelyanov of the Atlantic Branch of the Shirshov Institute of Oceanology (Russia). Co-chairmen of the IAMG Session were Profs. John Davis of the Kansas Geological Survey (USA) and Jan Harff of the Baltic Sea Marine Institute and Greifswald University (Germany). Technical presentations on all aspects of geology and oceanography of the Baltic Sea were held in the Kaliningrad Historical Museum. The IAMG Session was held on board the R/V Akademik Mstislav Keldysh, an historic research vessel anchored at the Museum of the World Ocean. Selected papers from the GIS session will appear in a special issue of Natural Resources Research, along with papers on quantitative topics (modeling, statistical analyses, etc.) from the general sessions.
R/V Akademik Sergey Vavilov

All 180 participants in the conference were housed on board the R/ Coffee break in V Akademik Sergey Vavilov in Kaliningrad harbor. In addition to the Kaliningrad Historical the technical sessions, there was a marine field trip for participants Museum to the Kaliningrad barrier island and a bus trip to the world-famous Baltic amber mines. The trips provided opportunities to examine Quaternary stratigraphy of the Baltic coast and coastal changes caused both by regional uplift and by human activities.

Meeting of German Hydrogeology Association University of Greifswald starts a special (FH-DGG) May 9-12, 2002 in Greifswald binational training center in Hanoi, Vietnam
Every two years German hydrogeologists meet in order to discuss new developments in research, analytical devices, remediation techniques, as well as strategies to meet legal directives, e.g. the recently developed European guidelines for ground and surface water (EU-WRRL). This year more than 200 scientists and practitioners met at Greifswald, where the chair for Applied Geology/Hydrogeology was newly installed only three years ago. As usual, the atmosphere was great, which was also due to the fine weather, marvelous landscape at the Baltic Sea and the big support by Greifswald’s students at the Institute for Geological Sciences. During three parallel sessions, 70 oral contributions and about 50 posters were discussed. Subjects like regional hydrogeological aspects (Mexico, Indonesia, Vietnam and many other countries), groundwater recharge and soil water quality, groundwater modeling and spatial heterogeneity of aquifers were presented. Especially the last two subjects had strong mathematical aspects and could as well have been presented at an IAMG meeting. The highly positive attitude of hydrogeology(-ists) toward mathematical modeling tools is well known, but it was again emphasized by the big interest for the two workshops which preceded the meeting: while H.-J. Diersch (WASY GmbH/Germany) presented the special facilities of his groundwater modeling program FEFLOW to simulate density driven flow and transport, H. Burger and M.-Th. Schafmeister highlighted the possibilities of geostatistics to deal with special problems in soil and groundwater contamination, regionalization and parameter identification for groundwater models. The meeting was concluded by two field trips in the vicinity of Greifswald on the Baltic Sea: one presenting the Holocene development of the Baltic coast at the island of Usedom, the second dealing with swamps and springs in the chalk cliffs at Rügen. Having organized this hydrogeologists meeting in Greifswald in May and being involved in the organization of the upcoming IAMG meeting in Berlin in September, I would strongly recommend (i) that Hydro-Geologists and Mathematical Geologists renew their close contact and (ii) that the participants of the Berlin meeting in September consider the possibility of visiting Germany’s Baltic coast. See you in Berlin Maria-Th. Schafmeister On March 25, 2002, the Joint Education and Training Center HanoiGreifswald (JETC) was officially opened in the presence of high-ranking representatives of academia and government of both countries, Vietnam and Germany. The JETC is affiliated to Greifswald University and operates within the buildings of the Hanoi University of Sciences. The main goal of our Center is to establish a one-year training program, the Joint Graduate Education Program (JGEP), which promotes especially gifted Vietnamese bachelors who wish to take up a PhD study in Greifswald, Germany. The motivation is to overcome the gap between the degrees of ‘Bachelor’ (Vietnam) and ‘Diploma’ or ‘Masters’ (Germany), caused by the differences in educational structures. Special courses are held by lecturers from both the German and Vietnamese partner-universities, which aim at the special field of PhD study. Today we cover five fields of interest: environmental geosciences, biotechnology, biomathematics, physics and community medicine. These disciplines have not been chosen randomly. It is obvious that these five disciplines reflect strongly the special needs of Vietnam, a country characterized by a big population growth rate and consequently a growing need for food (rice, vegetables, fish), a high potential in natural reserves, severe environmental problems and natural hazards like soil and water contamination, landslides, coastline regression, and ground and surface water salinization, phenomena naturally or artificially induced having strong effects on human life conditions and health. But Vietnam can as well be characterized as a country with a big potential for young students committed to science and knowledge. JETC combines three factors: interested and motivated Vietnamese students, a high demand for research, and German expertise within a framework of training and research activities. In order to keep the costs as low as possible for Vietnamese students, all courses take place in Hanoi. Twice a year German lecturers visit Hanoi to oversee examinations and teach special courses (spring School). Only successful program participants are then ready to start their PhD study in Germany. During February/March 2002, 30 lecturers held the first classes for more than 60 interested candidates; 50 percent being geoscientists, who – among other courses – completed their formation in fields like coastal processes, mineral-phase analysis, and geochemistry. The broad field of mathematical geology was represented by courses on basin modeling (Jan Harff) and geostatistics (Maria-Th. Schafmeister), respectively. Our program is not yet complete: other relevant special courses are yet to be included. The departments of Social Sciences, Law, and Languages have already been asked to develop similar programs. But even at this early stage of our program, which is funded for an initial period of three years starting in September, 2001, by the German Academic Exchange Office (DAAD), the high response of Vietnamese students proves the need for this kind of international exchange of knowledge, students, and scientists. For further information contact Maria-Th. Schafmeister, organizer of the DAAD-program ‘JETC Hanoi-Greifswald’ (Greifswald University, schaf@uni-greifswald.de) or visit our web-page (http://www.unigreifswald.de/~geo/Vietnam/index.htm).

The first Geostatistics-UK meeting for over ten years was held at the University of Leicester on 22 November 1999. The meeting was planned, organised and run by Dr. Alison Riding (ADAS, Research Division), Dr. Nick Tate (Department of Geography, University of Leicester) and myself. For Geostats-UK’99 a field of nationally and internationally recognised presenters was assembled around three core themes of geostatistics (i) characterisation of spatial variation, (ii) spatial prediction and (iii) spatial simulation. Each theme was the focus of a session in the oneday meeting and comprised a presentation by an invited keynote speaker, supported by three additional oral papers and several poster papers. The three keynote speakers were Dr. Margaret Oliver (Department of Soil Science, University of Reading), Prof. Richard Webster (Rothamsted Experimental Station, Hertfordshire) and Prof. Peter Dowd (Department of Mining and Mineral Engineering, University of Leeds). To make the material presented at the conference as accessible as possible the International Association for Mathematical Geology (IAMG) provided sponsorship to produce a small soft-cover proceedings of full written papers. This was distributed at the actual meeting. Of the 18 papers presented, 11 papers made it into the published proceedings. The meeting was a great success, attracting a delegation of over 50 (with participants from countries including Belgium, Cuba, the Netherlands, Spain and Sweden). This number, while small relative to major conferences, facilitated intense interest and debate because of the common interest. Building on this initial success, the second Geostatistics-UK meeting was held at the University of Reading on 25-26 March 2002, organised by Dr. Margaret Oliver (Department of Soil Science, University of Reading). The second meeting was held in conjunction with the British Society of Soil Science (BSSS), and the International Soil Tillage Research Group (ISTRO) Tillage Erosion and Translocation Working Group (TEGWG). GeostatsUK’02, therefore, was larger than Geostats-UK’99, spanned two days rather than one and attracted a larger international delegation of over 70. The meet—>

ing was organised into four sessions with a keynote speaker associated with each: Professor B.W. Silverman, FRS — Wavelets; Dr. M.V. Meirvenne — Geostatistical Assessment of the Risk of Exceeding a Site Specific Contamination Threshold; Dr. G.B.M. Heuvelink — Incorporating Process Knowledge in Spatio-Temporal Interpolation of Environmental Variables; Dr. I. Clark — Using Relationships Between Measurements to Improve Prediction: Illustrated by a Case Study in Aquifer Pollution Selected papers from Geostats-UK’99 are scheduled for publication as a special issue of Geographical and Environmental Modelling in 2002. A second special issue of Geographical and Environmental Modelling is planned based on papers from Geostats-UK’02. In addition, GeostatisticsUK now has its own dedicated web-site with the following address: http:// boris.qub.ac.uk/gis/gsuk/index.htm . The programme of both meetings can be found at this site. Arrangements are currently being put in place for a sixth meeting in 2004, and details of this will be posted shortly on the Geostatistics-UK web-site. We hope to see you at the next GeostatisticsUK meeting. Professor Peter Atkinson Department of Geography, University of Southampton

News from Freiberg
Geoinformatik (Geoscience Informatics) – A New Curriculum at Freiberg (Germany) University of Mining and Technology Since this winter term 2001/2002, Freiberg University of Mining and Technology offers a new diploma curriculum entitled “Geoinformatik” which translates to “Geoscience Informatics”. The new curriculum is jointly organized by the department of geosciences and the department of mathematics and computer sciences and offers students a well balanced combination of sciences (geological, physics, chemistry), applied mathematics and computer sciences directed towards geoscience applications of informatics which encompass the entire scope of geological science. Informatics is the study of information technology, its development and application. Geoscience informatics is the field of study that deals with the collection, processing, availability and dissemination of geoscience data, analytical and numerical modeling of processes in the geo-sphere described by the data, and presentation and communication of geo-information and knowledge with digital media. It is based on methods of applied mathematics and informatics as well as on explorative methods for the geo-sphere and inferential methods for its governing processes. The creative combination of both informatics and geoscience methods is required for successful applications of geoscience informatics in geoscience education, research, exploration, and enterprise. Relevant technologies and approaches include the formal study of geological information seeking and use, knowledge analysis and storage, user behavior and cognition, retrieval analysis, and preservation of information. Practical use of the Internet and Web, data mining, artificial intelligence and electronic publishing are but a few of the future applications. Geoscience informatics incorporates virtually all areas of geology’s affiliates including: Environmental Geology, Hydrogeology, Engineering Geology, Economic Geology, Energy and Mineral Resources, Geophysics, Geodesy, Tectonics, Volcanology, Petrology, etc. The graduate programme of Freiberg’s curriculum features Geodynamics, Numerical Modeling of Solid and Fluid Media, Management of Natural Resources, and Geomonitoring. For more and continuously updated information the reader is referred to http://www.geo.tu-freiberg.de/geoinformatik (in German). Personal information available upon request from the Dean for Students Affairs, Helmut Schaeben. PhD for K. Gerald van den Boogaart K. Gerald van den Boogaart received his PhD from the Department of Mathematics and Computer Sciences of Freiberg University of Mining and Technology, Germany, on completion of his PhD thesis “Statistics for individual crystallographic orientation measurements“ supervised by Helmut Schaeben. The objective of the thesis is the development of methods for the statistical analysis of crystallographic orientation data stemming from automated electron back scatter diffraction (EBSD) orientation measurements. Crystallographic orientations differ from other statistical data by their scale and their spatial dependence. As left cosets of rotations they do not belong to any of common scales of statistical data, and for physical reasons they do not generally comply with the independence assumption of classical statistics. To handle this non-linear scale the statistical moments are replaced by the C-coefficient derived from the characteristic representations of the corresponding group. They provide a simple method to consider crystallographic symmetries and to correct estimators for their bias. Moreover, the crystallographic exponential family is introduced for this scale. Two independent and complementary stochastic models of the spatial dependence are developed and applied to infer the variance of estimators. The first approach, motivated by the notion of crystal grains, allows to infer the estimation error based on knowledge of the microstructure. It requires some restrictive assumptions concerning the interaction between grains. The second approach, motivated by spatial statistics, is based on the sole assumption of a known finite range of dependence and applies generally. The theory provides for the first time the means to do quantitative orientation data analysis including simulation conditional to a distribution and a spatial dependence estimated from experimental data. Diploma for Katrin Lademann Katrin Lademann received her Diploma in Geology from the Department of Geology, Geotechnology and Mining of Freiberg University of Mining and Technology, Germany, on completion of her diploma thesis "Texture and microstructure investigations of high-grade metamorphics of the Saxonian granulites" supervised by Helmut Schaeben and Uwe Kroner (kroner@geo.tu-freiberg.de). The objective of her thesis was to clarify some aspects of the intricate relationship of texture and microstructure. She combined analysis of individual orientation measurements with electron back-scattering diffraction (EBSD) and orientation mapping with classical methods of microstructural analysis. Her major result is to have shown that a unique crystallographic form, the positive rhombohedra, predominates the development of lattice preferred orientation as well as the orientation of grain boundaries in quartz during dynamic recrystallization at high temperatures and pressures. She will continue her studies as a PhD student in the graduate college of spatial statistics. Diploma for Alexander Brenning Alexander Brenning received his Diploma in Applied Mathematics from the Department of Mathematics and Computer Sciences of Freiberg University of Mining and Technology, Germany, on completion of his diploma thesis ?Geostatistics without stationarity assumptions within geographical information systems“ supervised by Helmut Schaeben. The objective of this thesis is to relax the assumption of stationarity to generic stationarity and account for the relative lack of structure imposed on the process by additional data as usually stored in a GIS. Generic stationarity reflects the belief in the existence of natural laws that determine a process’ distribution law depending on local geology. It provides a means for stationarizing instationarity conditional on local geology in the sense that “the less stationary” the process is the more additional knowledge of local geology is necessary to determine the process’ distribution laws. Thus, the concept of process stationarity is replaced by a stationarity of the governing influence relating the local semivariogram and the local geology as stored in a Geographical Information System (GIS). A construction method is used which can meaningfully incorporate additional spatial information from a GIS like smoothly varying geology in the investigated area or geological faults interrupting continuity, mountainous morphology inducing spatially varying anisotropy, soil and hydrogeological properties, measured contaminant concentrations, etc. Least-squares parameter estimation is used to fit instationary semivariogram models in typical example situations, leading to non-linear optimization problems. Many situations of local anisotropy can be modeled using the class of elliptical semivariograms, which was studied in detail. Using the code developed for the present work, such models were successfully fitted, and in an example situation it could be seen that the corresponding kriging results are also consistent with our knowledge of local anisotropy of the process, in contrast to isotropic or geometrically anisotropic semivariograms.

A Workshop to take place immediately following the IAMG2003 conference in Portsmouth, UK on September 14, 2003. Convenor: Cyril A. Pshenichny, Petrography Dept., Faculty of Geology, St. Petersbur State University, Universitetskaya g Naberezhnaya 7/9, 199034 St. Petersburg, Russia, email: pshenich@kp1306.spb.edu Investigation of Geologic Reasoning as a New Objective of Geoscience and Geohazard Assessment Geology is a realm of both logic and intuition. We are going to pursue the paths the mind follows when studying geologic phenomena - the lines of induction and deduction, webs of analogies, tales of experience and prescriptions of models. This will be a collective adventure of scientists, from geologists to philosophers (and whomever else interested), aiming to give a new vision of geoscience, in which philosophic concepts turn into a computer string, and intuition of every geologist is given strict form and becomes common treasure of science. In advance of the workshop, Dr Pshenichny will this year be launching an email discussion group on logic and reasoning in geoscience: for further information and to join this group, or for further information about the planned workshop, please send him an email at pshenich@kp1306.spb.edu.
