REMINDER The deadline for abstract submission for GeoMod2004 (FEBRUARY 15, 2004) is approaching. Abstracts can be submitted on-line through the conference website at: http://www.ogs.trieste.it/GeoMod/ The GeoMod2004 conference "From Mountains to Sedimentary Basins: Modelling and Testing Geological Processes" brings together geoscientists from universities and industry who deal with analogue and/or numerical models. The meeting takes place in Emmetten (Lake Lucerne), Switzerland from June 9-11, 2004 and will cover the following main topics: 1. Surface Processes 2. Orogenesis 3. Sedimentary Basins 4. Fractures, Faults and Fluid Flow 5. Geological Predictions 6. Methods and Techniques We particularly encourage contributions in which modelling results are tested against real-world case studies, or compared with results from other model studies. The number of participants is limited to 150. A pre-conference analogue and numerical benchmark test will be held on June 8, 2004 and modelling labs from Amsterdam, Bern, Florence, Kingston, Kyoto, Parma, Potsdam, Rennes, Rome, Rueil Malmaison, Toronto and Uppsala have already expressed their interest in participating. Post-conference field trips are offered on June 12, 2004. To ensure the widest possible distribution of contributions, participants are invited to submit extended abstracts (max. 4 pages) which will be published in a special issue of the international journal Bollettino di Geofisica. Invited speakers Knut Bjorlykke (Oslo), Stephane Bonnet (Rennes), Jean Braun (Canberra), Sierd Cloetingh (Amsterdam), Stephan Duppenbecker (BP), Susan Ellis (Lower Hutt, NZ), Taras Geryas (Bochum), Didier Granjeon (IFP), Nina Kukowski (GFZ Potsdam), Martin Perlmutter (Chevron-Texaco), John Tabor (Shell), Bruno Vendeville (Austin), Johannes Wendebourg (Shell).
