Paleozoic
251.902 - 541 Ma



ID: 3025421
"Glenarm Wissahickon" formation

Age: Phanerozoic (251.902 - 541 Ma)

Stratigraphic Name: Glenarm Group

Description: Lithologically similar to oligoclase-mica schist of the Wissahickon Formation (PZw), but also includes lenticular amphibolite bodies having ocean-floor basalt chemistry.

Comments: Digital map differences from 1980 printed map: name and map symbol changed from (Wissahickon Formation - eastern part) (Xw).
