The crystalline rocks of South Carolina

A provisional geologic map of the western half of South Carolina showing the crystalline rocks and the edge of the overlapping sediments of the Atlantic Coastal Plain was prepared in 1960 at a scale of 1:250,000 and published by the U.S. Geological Survey in 1965 as Miscellaneous Geologic Investigations Map I-413. The present report is a description of the crystalline rocks depicted on that map.
