Paleoproterozoic
1600 - 2500 Ma



ID: 2755899
Metamorphosed Shale

Age: Proterozoic (1600 - 2500 Ma)

Description: Gray to dark-gray phylite, slate, and mica schist. Estimated thickness at least 5,000 ft (1,524 m).

Lithology: Major:{phyllite,slate,mica schist}

Paleoproterozoic
1600 - 2500 Ma



ID: 2472233
Metamorphosed shale

Age: Proterozoic (1600 - 2500 Ma)

Description: Gray to black slate, phyllite, or schist. In part, garnetiferous at higher metamorphic grade. Locally carbon-rich and contains sulfide minerals. Includes Grizzly Formation (Dodge, 1942), part of Swede Gulch Formation (Bayley, 1972c), and part of Oreville Formation (Ratté and Wayland, 1969). Thickness poorly known due to homogeneity and intense folding, but estimated to be at least 2,000 m.
