Abstract:

BASIN is a finite-element program, that simulates the filling of a sedimentary basin and includes transport, erosion and consolidation of sediment, tectonic processes like isostatic compensation, consolidational fluid flow, topography driven fluid flow, heat flow including advection, solute transport. It incorporates a physically consistent compaction model based on the equation of state for porosity. A description of some underlying principles can be found in Bitzer (1994) and Bitzer (1996). BASINVIEW is a visualisation tool for fast analysis of simulation results. Results from experiments with BASIN may be quite numerous (in some cases may exceed 600 files) and BASINVIEW is a fast visualisation tool designed to work with GhostScript.

So far, only distensive basin configurations have been analysed by other authors. BASIN, however, is capable of modeling compressive situations as well. Such situations are much more difficult to handle because of the extreme changes of basin geometry due to the compression. BASIN does not provide a structural simulation. Instead, the presumed structural evolution is used as input data in order to simulate subsidence, fluid flow, heat flow and evolution of petrophysical data like porosity, compressibility etc. A simple molasse-like experiment showing a compressive basin with thrust sheets ariving from the right can be viewed as a computer animation. The file has about 1 Mb and you will need Sparkle to visualize it. The experiment demonstrated in the film applies only few elements, however it contains some of the basic features of a molasse basin.
Graphics created with BASINVIEW can be printed on any printer. Another version (AIBASIN) creates Adobe Illustrator files that allow further graphic operations.
