Geology and geothermal resources of the Rexburg Area, eastern Idaho
A brief description of major Cenozoic geologic features of the Rexburg area and a discussion of their geothermal significance are presented. The study area, identified as having geothermal potential, is approximately circular, about 55 km across, and centered on the town of Rexburg. It is roughly coextensive with a complex of about eight calderas of Pliocene age, here named the Rexburg caldera complex. These calderas were the source of several major rhyolitic volcanic deposits present along the southeast margin of the eastern Snake River Plain. The geology of this area was previously mapped in reconnaissance (Prostka and Hackman, 1974) and much of it as remapped in detail in 1977 because of its recognized geothermal potential.
