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

Pliocene - Miocene
2.588 - 23.03 Ma



ID: 3006363
Younger tuffaceous sedimentary rocks

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Horse Camp Formation; Esmeralda Formation; Belted Range Tuff; Timber Mountain Tuff; Paintbrush Tuff; Crater Flat Tuff; Muddy Creek Formation; Siebert Tuff

Description: Tuffaceous and other young Tertiary sedimentary rocks. Most of these rocks are sedimentary with a strong volcanic component - a few are tuffaceous with a strong sedimentary component. This unit includes rocks originally mapped as the High Rock sequence in Washoe County; the Horse Camp Formation in northern Nye County; the Esmeralda Formation in Mineral and Esmeralda Counties; older lake beds in Lincoln County; the Belted Range Tuff; the Indian Trail Formation (now abandoned); Timber Mountain, Paintbrush, and Crater Flat Tuffs; Wahmonie and Salyer Formations in southern Nye County; the Siebert Tuff in Esmeralda County; the Muddy Creek Formation in Clark County; and the Thousand Creek and Virgin Valley “beds” in Humboldt County; and other unnamed units. It corresponds to units Ts3 and Tts from the 1978 State map. It is present in all counties.
