This symposium on 'Computerized Basin Analysis for Prognosis of Energy - and Mineral Resources' was organized by Dr. Jan Harff, chairman ofthe Scientific Committee for the meeting, in Giistrowin what was then East Germany. Sponsors ofthis meeting were the International Union of Geological Sciences' Commission on Storage, Automatic Pro­ cessing and Retrieval of Geologic Data (COGEODATA), Academy of Sciences of the German Democratic Republic (GDR), National Oil and Gas Trustofthe GDR, and the International Association for Mathematical Geology (IAMG). Main topics of the symposium, held from 19-22 June 1990, were application of computer methods to the exploration and exploitation of oil and gas, coal, and other energy and mineral resources. There were computer demonstrations as well as a one-day field trip to the geothermic heating plant in Waren. The Regional Group for Eastern Europe of COG EO DATA also met during the conference. Fifty-one papers were presented including eight poster sessions by authors from 14 countries. As was to be expected, there was a large percentage of papers from the East Bloc of European countries, especially the GDR, USSR, and the CSSR with a fair representation from the FRG and USA and a smattering from the nine others. Most of the papers were application oriented and related to the mineral industries. There was ample time for exchange of ideas and dissemination of material.
