Paradox Basin, UtahDownload paradox6.sim ... This Landscape File shows geologic information for the Paradox Basin region in southeastern Utah and southwestern Colorado, USA. This is a petroleum-producing area with a relatively simple, layer-cake, geologic structure. The single texture layer fuses a geologic map with relief shading and also shows the basin outline and state boundaries. The overlay layer shows the use of the color stack side style with extruded solid polygons. Each of the six circular polygons represents a reconstructed section of rock units for that particular location, using data from the United States Geological Survey. The solid polygons extend both above and below the surface. The portions above the surface show inferred sections of units that once covered that location, but have been eroded away in the recent geologic past. The portions below the surface show the sequence of rock units still preserved in the subsurface. You can view the above-ground and below-ground portions of the solid polygons at the same time by using the View menu to set the TNTsim3D main view to Wireframe mode. Each solid polygon has a database record for the top of the section and for each rock unit boundary, with extrusion based on the elevation attribute values recorded in these records. The styles for the color stack on the sides of the polygons are assigned using another table containing the rock unit names.
