A 1:75,000-scale, color geologic map of the 34 Ma Caetano caldera, Lander and Eureka counties, Nevada with descriptions of 41 geologic units and one cross section. Accompanying text includes full unit descriptions and references. More than 100 percent extension beginning in the middle Miocene tilted the caldera into a set of about 40-degree east-dipping fault blocks that provide exceptional exposures of the entire caldera to its floor, including Paleozoic sedimentary rocks and pre-caldera volcanic rocks in the floor, intracaldera Caetano Tuff up to 4 km thick, ash-flow tuff feeder dikes, caldera collapse breccias, post-collapse resurgent intrusions, and the caldera structural margin and topographic wall.

The GIS files for this map were made available by the Nevada Bureau of Mines and Geology in cooperation with the U.S. Geological Survey STATEMAP Program.

GIS folders contain the following files:

The symbol and image files listed above contain graphic symbol information about
associated line, point, and polygon features found on the published map
but that may not have been fully identified in the present format of the feature line,
point, or polygon attribute file. The layer files are provided here for use with
the geologic map digital conversion as an aid to a graphic presentation of the full
data set. The files can be utilized in ESRI ArcGIS 10.3.1.

Conversion Process: The published map was scanned, digitized, and attributed using ESRI ArcGIS Desktop 10.3.1 software.
