Short summary
The Hurricane fault is a major and active normal fault located in the southwestern USA. This study utilizes the geochemistry and dating of calcite veins associated with the fault to characterize ancient groundwater flow. Results show that waters moving along the fault over the last 540 000 years were a mixture of infiltrating fresh water and deep, warm salty groundwater. The formation of calcite veins may be related to ancient earthquakes, and the fault influences regional groundwater flow.
