“…Both of these structures can extend into the ductile regime creating feedback loops as fluids are transported upwards weakening the brittle crust toward the ductile regime in turn locally decreasing the depth of the BDT (Cheng & Ben-Zion, 2019;Sibson, 1984Sibson, , 1992Wannamaker et al, 2004). 2), known mineral occurrences (McFaul et al, 2000), earthquake hypocenters within each depth range, and mapped faults (gray lines). Earthquakes, mineral deposits, and geothermal resources often occur in less conductive material and near the boundaries of high conductance.…”

Modern and ancient hydrothermal systems are associated with a variety of recoverable resources. Modern systems can be harnessed to produce electrical or heat energy (e.g., Hamm et al., 2019), whereas ancient hydrothermal systems could have deposited mineral resources in recoverable abundances (e.g., John, 2001;Tosdal et al., 2009). Whether ancient or modern, all hydrothermal systems require (a) an interconnected network of porosity through which fluids can circulate and (b) a heat source to drive circulation. The heat source of a hydrothermal system can play a significant role in controlling commercial development, including affecting the size, depth, and chemistry of the mineralizing or circulating fluids. Therefore, imaging crustal control on deep heat sources and fluid pathways toward the near surface provides critical information for locating and characterizing potential resources.The Gabbs Valley area in west-central Nevada encompasses the eastward transition from Walker Lane dextral strike-slip tectonics to Basin and Range extensional tectonics (Figure 1). Several known modern and ancient hydrothermal systems, including multiple commercial mineral deposits, are located in the Gabbs Valley area. Three known modern hydrothermal systems exist in the Gabbs Valley area: (a) the Don A. Campbell geothermal system, which supports a 39 MWe power station that produces electricity from ∼125°C hydrothermal fluids (Orensein & Delwiche, 2014), (b) the southeastern Gabbs Valley (SGV) geothermal system with temperatures of 125°C at 150 m depth (Craig, 2018;Craig et al., 2021), and (c) Rawhide hot springs which has a surface temperature of 60°C and geothermometry as high as 130-140°C (Kratt et al., 2008). Both Don A. Campell and SGV are blind,

Alternatively, certain national databases encompass mine records of every sort: active and inactive, underground and aboveground, and mine offices to mega-pits (McFaul et al, 2000). With mines continually phasing in and out of operation, keeping track of the areal extent of mines and changes in mining footprints (such as expansions, reclamations, and closures) across the conterminous United States in an accurate, consistent manner is a complex undertaking.…”

Mapping Extent and Change in Surface Mines Within the United States for 2001 to 2006

et al. 2015

A complete, spatially explicit dataset illustrating the 21st century mining footprint for the conterminous United States does not exist. To address this need, we developed a semi‐automated procedure to map the country's mining footprint (30‐m pixel) and establish a baseline to monitor changes in mine extent over time. The process uses mine seed points derived from the U.S. Energy Information Administration (EIA), U.S. Geological Survey (USGS) Mineral Resources Data System (MRDS), and USGS National Land Cover Dataset (NLCD) and recodes patches of barren land that meet a “distance to seed” requirement and a patch area requirement before mapping a pixel as mining. Seed points derived from EIA coal points, an edited MRDS point file, and 1992 NLCD mine points were used in three separate efforts using different distance and patch area parameters for each. The three products were then merged to create a 2001 map of moderate‐to‐large mines in the United States, which was subsequently manually edited to reduce omission and commission errors. This process was replicated using NLCD 2006 barren pixels as a base layer to create a 2006 mine map and a 2001–2006 mine change map focusing on areas with surface mine expansion. In 2001, 8,324 km2 of surface mines were mapped. The footprint increased to 9,181 km2 in 2006, representing a 10·3% increase over 5 years. These methods exhibit merit as a timely approach to generate wall‐to‐wall, spatially explicit maps representing the recent extent of a wide range of surface mining activities across the country.

The U.S. Census Bureau has projected that the United States population will surpass 360 million by the year 2030 with considerable growth projections in those states having significant incidences of ultramafic, igneous, and metamorphic rock formations (i.e., CA, AZ, NV, OR, WA, VA, NC, etc.)…”
