| Paleozoic - Proterozoic 251.902 - 2500 Ma ID: 2865444 | Baltimore Gabbro Complex Age: to Triassic (251.902 - 2500 Ma) Stratigraphic Name: Baltimore Gabbro Complex Description: Hypersthene gabbro with subordinate amounts of olivine gabbro, norite, anorthositic gabbro, and pyroxenite; igneous minerals and textures well preserved in some rocks, other rocks exhibit varying degrees of alteration and recrystallization with a new metamorphic mineral assemblage. 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).
