Summary

Regional geophysical maps of the Great Basin, USA were generated from new and existing sources to support ongoing efforts to characterize geothermal resource potential in the western US. These include: (1) a provisional regional gravity grid that was produced from data compiled from multiple sources: data collected by the USGS and Utah Geological Survey under various projects, industry sources, and regional compilations derived from two sources: a Nevada state-wide database (Ponce, 1997), and a public domain dataset (Hildenbrand et al., 2002), (2) a regional magnetic grid derived from the North American magnetic compilation map of Bankey et al. (2002) and, (3) a regional depth-to-basement grid derived from Shaw and Boyd (2018). References: [...]

Purpose

These datasets were compiled to support projects conducted under, and with support from, the USGS Energy Program’s Geothermal Resource Investigations Project, and the INGENIOUS (Innovative Geothermal Exploration through Novel Investigations of Undiscovered Systems; https://gbcge.org/current-projects/ingenious/) project funded by the U.S. Department of Energy Geothermal Technologies Office under award DE-EE0009254 to the University of Nevada, Reno. INGENIOUS is a multi-disciplinary, multi-institutional effort to develop new methodologies and best practices to accelerate the discovery of new, commercially viable hydrothermal resources.
