“…The presence of an elevated (realtive to crustal values) 3 He/ 4 He signature in shallow geothermal fluids can arise through direct mixing with mantle derived fluids or by the interaction of geothermal fluids with young, mantle derived magmatic rocks van Soest, 2007, 2006;Kennedy et al, 1997;Kulongoski et al, 2005;Torgersen and Jenkins, 1982). Magmatic geothermal systems occur along the periphery of the Great Basin, throughout the western United States and around the world (e.g., Moeck, 2014).…”

a b s t r a c tGeothermal fluids produced from two of the largest production geothermal fields in the Great Basin have helium isotope ratios that are anomalously high relative to basin-wide trends. These data indicate that the geothermal systems, Dixie Valley, Nevada and McGinness Hills, Nevada have an anomalously high fraction of mantle derived fluid. These connections to deeply derived fluid and heat may supplement crustal heat production and be responsible, in part, for the anomalously high production capacity, relative to other Great Basin geothermal fields, that Dixie Valley and McGinness Hills support. Deep-seated crustal structures across the Great Basin and around the world are known to be associated with structural reactivation, can have relatively high permeability, and can act as fluid flow conduits. These deep seated structures across the Great Basin control upflow of deeply derived heat and fluids into the shallow geothermal systems at Dixie Valley and McGinness Hills, contributing to their productivity.

“…Newell et al (2005) show that in western North America the highest contribution of mantle helium correlates to the youngest and most active tectonic regions and domains of the lowest mantle velocity. As to transport of gases to the surface, Kulongoski et al (2005) concluded that mantle helium, found in ground waters of the Morongo Basin east of the San Andreas fault, moved via deeply penetrating faults. They also speculate that episodic seismicity and associated hydrofracturing drive volatile transfer from the mantle to the crust.…”

Below melting temperatures, fluid flow represents the most common form of chemical transport in the crust (Fyfe, 1978;NRC, 1990), thus pore fluid chemistry and geochemical tracers are essential in constraining sources, sinks and timescales for fluid flow.…”

Helium measurements of pore fluids obtained from the San Andreas Fault Observatory at Depth (SAFOD, USA) drill cores

4He accumulated in fluids is a well established geochemical tracer used to study crustal fluid dynamics. Direct fluid samples are not always available; therefore, we have adapted a method to extract rare gases from matrix fluids of whole rocks by diffusion. Helium was measured on matrix fluids extracted from sandstones and mudstones recovered during San Andreas Fault Observatory at Depth (SAFOD) drilling. Samples were typically collected as subcores or from drillcore fragments.
