This dataset is a composite of part or all of the twelve 1:250,000 scale quadrangles that make up Oklahoma. The result looks like a geologic map of the State of Oklahoma. But it is only an Oklahoma shaped map clipped from the 1:250,000 geologic maps. This is not a new geologic map. No new mapping took place. The geologic information from each quadrangle is available in the composite dataset.
This dataset was developed to provide geologic map GIS database of Oklahoma for use in future spatial analysis by a variety of users.
This database consists of Arc/Info GIS datasets: - ok_geology, the formations and contacts, - ok_faults, the faults, - ok_folds, the folds

Joel R. Cederstrand, prepared and released the original 12 Oklahoma 1:250,000-scale quadrangle geologic maps and county maps as OFR-96-370 to ORF-96-381. Greg Green, joined the 12 sheets and attributed the polygons with text files created by Doug Stoeser and Bill Heran. All are with the U.S. Geological Survey.

Digitized from 1:250,000 scale maps
Greg Green assembled the 12 maps, Bill Heran created the cross map correlations, and Doug Stoeser created the single map sheet and colors.
Cederstrand created the digital 1:250,000 versions of the orginal paper maps. Stoeser and Heran entered the formation description from the paper maps into spread sheet text files. Green joined these text attributes to the digital maps and merged the sheets together.
