Early Oligocene - Middle Eocene
28.1 - 47.8 Ma



ID: 2856665
Older andesite and intermediate flows and breccias

Age: Paleogene (28.1 - 47.8 Ma)

Description: Unit includes andesite or dacite flows, flow breccias, and hypabyssal rocks in Lander County, andesitic to latitic flows, pyroclastic rocks, and phenoandesitic and phenolatitic flows in Elko County, and other undifferentiated volcanic rocks in other counties. Present in Humboldt, northern Nye, Churchill, Elko, Eureka, Lander, and White Pine Counties. It corresponds to the 1978 State map unit Ta1.
