1:62,500-scale, full-color Geologic Map of the Austin 7.5' quadrangle in Lander County, Nevada, with 4 cross sections and description of 30 units. The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for a variety of geologic maps. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends.
