Geologic Atlas of Texas viewer

Open Viewer

The new Texas Geology Web Map Viewer is an interactive web-based tool that allows a broad range of users to explore the geology of the Lone Star State at a scale of 1:250,000. Users can navigate the map with a simple click-and-point tool, or by using the location search tool to search for common geographic place names, latitude/longitude coordinates, and other areas of interest. The interactive map viewer allows users to turn data layers on or off, identify layers of interest, and retrieve detailed information about each geologic formation, such as the feature name, geologic age, and feature description.

In October 2002, the USGS Texas Water Science Center, in cooperation with the Texas Natural Resources Information System (TNRIS), embarked on a project to digitize all 38 Geologic Atlas of Texas hardcopy map sheets from University of Texas-Bureau of Economic Geology (UT-BEG) and compile them into a single, stand-alone database. These data provide the backbone for the new Texas Geology Map Viewer.

Mapped rock units can include both groups and individual formations. You can subdivide groups or formations into smaller units called members. Mapped faults are symoblized with arrows showing relative movement.
