Journal Article: Hot Dry Rock Geothermal Energy in the Jemez Volcanic Field, New Mexico

Abstract
Large, young calderas possess immense geothermal potential due to the size of shallow magma bodies that underlie them. Through the example of the Valles and Toledo calderas, New Mexico, and older, more deeply eroded and exposed calderas, it is possible to reconstruct a general view of geothermal environments associated with such magmatic systems. Although a zone of anomalous heat flow extends well beyond caldera margins, high- to moderate-temperature hydrothermal systems appear to be restricted to zones along intracaldera faults and may account for only about five percent of the thermal energy available from the magmatic system. Much of the remaining thermal energy resides within caldera fill and 'basement' rocks under and along the flanks of the caldera and can only be extracted by manmade geothermal systems. Depending upon the age and cooling history, considerable thermal energy may still reside in crystallizing magma.
