Geologic map of the Jackass Flats Area, Nye County, Nevada

Technical Report ·
OSTI ID:59912

The Jackass Flats area is located in the southwestern Nevada volcanic field, a faulted, dissected volcanic plateau. The volcanic rocks are composed of silicic ash flows and subordinate lavas 16 to 6 My (million years) old (Byers and others, 1976a). This map has been compiled from nine 7 1/2-minute quadrangles that were mapped between 1961 and 1965. The usages of formal stratigraphic units and map unit descriptions were taken from those quadrangles and from Byers and other (1976a). Descriptions of the Crater Flat Tuff members and subunits and underlying tuffs were mainly derived from descriptions of core from drill holes USW-G1 and USW-G2.
