Geochemical exploration techniques applied to well waters of the South San Bernardino Geothermal Area and the Upper Santa Ana River Valley, California
Chemical geothermometry surveys of well waters in the Arrowhead Hot Springs, Bunker Hill Basin, and other basins located near San Bernardino, CA suggest temperatures up to 140C for waters ascending along fault zones. Calculated temperatures from geothermometry are nearly always higher than the measured temperatures of 87C at Arrowhead Hot Springs and 63C in a well sited on the Loma Linda Fault. Mixing of the geothermal waters with shallow, dilute groundwaters is indicated by ternary molality plots of C1, B, and HCO3 and C1, F, and HCO3. The source of the geothermal component appears to be deep circulation in fractured crystalline basement complex. Circulation at depth is enhanced and directed along the major strikeslip fault zones of the region.
