Laczniak, R.J, 2006, Boundary of the southwestern Nevada volcanic field from Laczniak and others (1996), for the Death Valley regional ground-water flow system study, Nevada and California: U.S. Geological Survey data release, https://doi.org/10.5066/P9767KIV.

Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital data set defines the boundary of the southwestern Nevada volcanic field (SWNVF), an area of thick, regionally distributed volcanic rocks within the Death Valley regional ground- water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. The SWNVF boundary encompasses an approximate 12,000 square-kilometer region and is based on a map of hydrogeologic controls on ground-water flow by Laczniak and others [...]

Purpose

The extent of the SWNVF (Laczniak and others, 1996) was used to distinguish the volcanic tuffs in the DVRFS. Based on geologic studies, it is thought that the volcanic rocks within the SWNVF, particularly those within a caldera boundary, may have different properties than those outside the SWNVF. As a result, the material-property zones for a number of the volcanic rocks were partially based on the extent of the SWNVF. These material-property zones were used to develop input zone-array files for the numerical ground-water flow model of the DVRFS.
