Abstract
The Los Alamos Scientific laboratory has been investigating a large area in New Mexico for Hot Dry Rock geothermal potential. The area includes parts of the Jemez volcanic lineament and the central Rio Grande rift. LASL has completed a detailed magnetotellurc/audiomagnetotelluric survey covering 161 square km over an area of high heat flow, south of Zuni, NM. We have also completed the data collection and preliminary analysis phases of a regional MT survey which suggest the Jemez lineament is associated with a crustal structure of anomalously high electrical conductivity. The detailed MT shows an average tipper strike of N60°E above 100 sec period, representing the structural trend within Precambrian basement. The Jemez lineament strikes approximately N55°E; this suggests a relationship between the Precambrian structure beneath the Zuni area and the Jemez lineament.
