Devonian
358.9 - 419.2 Ma



ID: 2922436
Muscatatuck Group

Age: Devonian (358.9 - 419.2 Ma)

Stratigraphic Name: Muscatatuck Group

Description: Limestone and dolomite

Comments: On the paper state map, there are two units, both with the same map pattern, labeled "D" and "D1". The only difference appears to be the relative abundance of the two major lithologies, limestone and dolomite. On the digital map, the unit is not subdivided.

Lithology: Major:{limestone,dolostone}
