Early Jurassic
174.1 - 201.3 Ma



ID: 2779470
Holyoke Basalt

Age: Early Jurassic (174.1 - 201.3 Ma)

Stratigraphic Name: Holyoke Basalt

Description: Greenish-gray to black (weathers bright orange to brown), fine- to coarse-grained, grading from basalt near contacts to gabbro in the interior, composed of pyroxene and plagioclase with accessory opaques and locally olivine or devitrified glass.

Comments: Part of Central Lowlands; Newark Terrane - Hartford and Pomperaug Mesozoic Basins. Part of Newark Supergroup (Upper Triassic and Lower Jurassic). Part of Meriden Formation of Krynine (1950) (Lower Jurassic); CT005. Original map source: Connecticut Geological and Natural History Survey, DEP, in cooperation with the U.S. Geological Survey, 2000, Bedrock Geology of Connecticut, shapefile, scale 1:50,000
