The Jornada del Muerto is a large basin located in the Rio Grande rift of south central New Mexico. Estimates of heat flow in deep petroleum tests within a large basin of the Rio Grande rift, which has suffered little syn-rift fracturing, may begin to provide clearer insight into the relationships between high heat flow and crustal thinning processes. Most heat flow data in rifts are uncertain largely because of hydrologic disturbances in regions of extensive fracturing. Heat flow and thermal processes in the Jornada delMuerto, New Mexico
