This map was prepared as part of the USGS Survey and Analysis project of the USGS to capture, convert, and make available in digital format state scale-maps. Purpose: This dataset was developed to provide a geologic map GIS database of Texas for use in future spatial analysis by a variety of users. Supplemental_Information: This database consists of ArcInfo GIS datasets: - txgeology (formations and contacts) - txfault (faults) - txbar&ball (bar & ball symbols and thrust fault teeth) Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 2005 Currentness_Reference: publication date Status: Progress: Complete Maintenance_and_Update_Frequency: As needed Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -105 50 East_Bounding_Coordinate: -93 30 North_Bounding_Coordinate: 36 40 South_Bounding_Coordinate: 25 45 Keywords: Theme: Theme_Keyword_Thesaurus: none Theme_Keyword: geology Theme_Keyword: Texas Place: Place_Keyword_Thesaurus: none Place_Keyword: USA Place_Keyword: Texas Place_Keyword: TX Access_Constraints: none Use_Constraints: Any hardcopies utilizing these data sets shall clearly indicate their source.

Barnes compiled the state geologic map in 1992 from the 38-sheet 1:250,000 scale Geologic Atlas of Texas. Process_Step: Process_Description: Doug Stoeser, USGS, recognized the need and organized a team to prepare, integrate, and publishe the datasets for the Geology of Texas. Geologic Data Systems of Denver, Colorado redrafted, photographically enlarged, scanned, digitized, and attributed the map. Line-work was matched within the resolution of plotted lines. Nancy Shock, former USGS, but now with the National Park Service, closely monitored the digitizing. Greg Green, USGS, joined the 4 sheets and checked the attributes. Gayle Dumonceaux created Adobe Illustrator version of the geologic map used for review and quality assurance. Bill Heran hand checked the location and lithology of the igneous rock outcrops.
