Neogene
2.588 - 23.03 Ma



ID: 3186305
Cenozoic volcanic rocks

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Columbia River Basalt

Comments: Columbia Plateau

Lithology: Flood basalt(s); mafic volcanic rocks; basalt

ID: 2731449
Intermediate andesite and intermediate flows and breccias

Age: Cenozoic (15.97 - 33.9 Ma)

Stratigraphic Name: Mizpah Trachyte; South Willow Formation; Milltown Andesite

Description: Andesite flows and breccias and other related rocks of intermediate composition such as dacite, rhyodacite, quartz latite, and biotite-hornblende porphyries. This unit includes units mapped as the South Willow Formation on the Washoe North map, the Milltown Andesite on the Nye South and Esmeralda County maps, the Mizpah Trachyte on the Nye North map, and other units. It corresponds to unit Ta2 on the 1978 State map. It crops out in all counties except Clark, Eureka, Lyon, Douglas, and Carson.
