Geologic map schematic of the Coso volcanic field.

Geologic map schematic of the Coso volcanic field. White lines are heat flux values from Combs, 1980 (values 3, 5, 10, 15 HFU). Yellow lines are fault positions; blue diamonds represent rhyolite vent locationss and red squares represent basaltic vent locations younger than 0.3 Ma. HFU = 41.87 mW/m².
