Summary
This digital dataset represents the 3D fault and stratigraphic surfaces of the three dimensional geologic map of the southeastern Gabbs Valley, Nevada. The data define the easting, northing, and elevations (meters, NAD 83 Zone 11N) of points that define the top and bottom contacts of stratigraphic units and fault surfaces.
Summary
This digital dataset represents the 3D fault and stratigraphic surfaces of the three dimensional geologic map of the southeastern Gabbs Valley, Nevada. The data define the easting, northing, and elevations (meters, NAD 83 Zone 11N) of points that define the top and bottom contacts of stratigraphic units and fault surfaces.
This digital dataset was created as part of a U.S. Geological Survey study, and it contains x, y, and z point data that define the fault and stratigraphic surfaces of the three–dimensional geologic map of the southeastern Gabbs Valley Geothermal Area, Nevada. The elevation range of the map extends from ~1370 m at the land surface to a maximum depth of 2500 m below sea level. The three–dimensional map was constructed as part of the Nevada Play–Fairway Project, a regional effort to characterize new geothermal resources in the United States. The three–dimensional map was built by integrating the results from potential-field geophysical, geologic mapping, and three–dimensional gravity inversion modeling studies. Local data collection and analysis in southeastern Gabbs Valley, Nevada, which included construction of this three–dimensional map, lead to the drilling of six temperature gradient wells and identification of previously unknown 124.9°C hydrothermal fluids at 150 m depth. These high temperatures indicate that the southeastern Gabbs Valley hydrothermal system has temperatures that are comparable to developed geothermal fields in the region. This project was funded by a U.S. Department of Energy grant awarded to James E. Faulds at University of Nevada, Reno (grant number DE-EE0006731), by the Mendenhall Program of the U.S. Geological Survey, and by the Geothermal Resources Investigation Project (GRIP) funded by the Energy Program of U.S. Geological Survey.
