Personnel of the Department of Geology and Geophysics of the University of Utah are conducting research directed toward the design of exploration systems suited to detection, delineation, and evaluation of potential geothermal resources in the State of Utah. These systems will be tested An areas of known hot springs, late Tertiary or Quaternary volcanic activity, current microearthquake activity and in areas of known high heat flow. Photo-interpretation, geologic mapping, structural analysis, petrologic study, hydrothermal alteration studies, geochemical analyses, geothermometry, geochronology, microearthquake and seismic noise monitoring, heat flow measurement, self-potential surveying, resistivity/induced polarization surveying, electromagnetic sounding, magnetic surveying, and gravity surveying may be combined to maximize scientific yield while maintaining low costs in order to optimize the cost-effectiveness of each system. Other ingredients of exploration architecture shall be incorporated if considered desirable. It is anticipated that not all ingredients shall be used on any one prospect
