Abstract

The bedrock geology of Warren County consists of three ARC/INFO Geographic Information Systems (GIS) coverages. The GIS data were digitized from various published and unpublished 1:24,000 and 1:48,000 scale geologic maps compiled from 1987 to 1993. The "contacts" theme contains map polygons and lines of stratigraphic unit boundaries and fault traces. The "folds" theme contains line traces of antiforms and synforms in bedding and cleavage. The "tiles" theme contains polygons and lines of the county boundary and U.S. Geological Survey 7-1/2' quadrangles. The readme.txt file contains a list of the polygon and line variables used in these themes.

 These generalized maps show the geologic contacts, folds, and 7-1/2' quadrangle coverages included in DGS96-2. Fold traces depicted in the lower map are grouped into those occurring in Paleozoic rocks (red lines) and Proterozoic rocks (black lines).
