Paleozoic - Proterozoic
251.902 - 2500 Ma



ID: 2824500
Ultramafic Rocks

Age: to Triassic (251.902 - 2500 Ma)

Description: Chiefly serpentinite with partly to completely altered dunite, peridotite, pyroxenite, and massive to schistose soapstone; talc-carbonate rock and altered gabbro are common in some bodies.

Comments: Original map source: In 1995 the Water Resources Division of the U.S. Geological Survey digitized the geologic map of Maryland from the 1968 paper map (Reference MD001). Information about products from the Maryland Geological Survey can be found at http://www.mgs.md.gov/.
