- •
3He/4He indicate a high fraction of mantle fluid in some Great Basin geothermal systems.
- •
Upwelling mantle fluids carry heat which is supplemental to crustal heat production.
- •
Ancient crustal structures act as permeability conduits for upwelling fluids.
- •
Robust production at anomalous 3He/4He systems is partially due to mantle fluid supply.
