Heat flow data covering part of southwestern utah in the area approximately beteen the Cove Fort geothermal field and the town of Milford. This data was collected by the Utah Geologica Survey. The units are in mW/m2.

This PFA model is probability based and used a heat CRS which included (1) Quaternary basalt flows, (2) Quaternary rhyolite flows and domes, (3) heat flow, (4) Na/K geothermometers, and (5) magnetotelluric data and a fracture permeability CRS which included (1) magnetotelluric based rock conductivity, Quaternary fault density, seismic events, and gravity gradient data. The PFA model has three classes: Class 1 = high risk, Class 2 = moderate risk, and Class 3 = low risk for geothermal exploration.

The points in this shapefile show locations of silica sinters and hydrothermally altered (opalized/silicified) mio-pliocene fresh water limestone in the Twin Peaks and Cove Creek Dome areas in southwestern Utah. These were sample sites. The samples underwent x-ray diffraction analysis to determine mineralogy to determine the percent and type of opal present. This was for relative dating. Studies have shown that it takes approximately 40,000 years for hot spring related opal to transition to quartz, with transitions from opal-A, opal-CT, opal-C in between. The high concentration of opal CT in most of these samples may indicate that their age is similar to Opal Mound fault opal at Roosevelt Hot Spring (

This dataset represents the probability of rock conductivity being >=0.015, which was used in the Southeastern Great Basin play fairway analysis project, Phase 2, permeability composite risk segment. This dataset was derived by first calculating conductivity from magnetotelluric resistivity and then applying simple probability kriging with a cutoff of 0.015. This was used in Phase 2, Southeastern Great Basin Geothermal Play Fairway Analysis

This dataset represents the integration of heat data, including heat flow and Na/K geothermometer data, which was used in the Southeastern Great Basin play fairway analysis project, Phase 2, as a composite risk segment.  The input data were probability based so this dataset has been normalized between 0 and 1 for use in PFA.

This dataset represents the integration of fault density, seismic activity, gravity gradients, and magnetotelluric data that was used in the Southeastern Great Basin play fairway analysis (PFA) project, Phase 2, as a composite risk segment to represent potential fracture related permeability. This is the permeability dataset used in Phase 2, Southeastern Great Basin Geothermal Play Fairway Analysis. The input data were all probability based and this dataset has been normalized between 0 and 1 for use in PFA.
