This dataset is a composite of part or all of the 12 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 within the composite
