SE Great Basin Play Fairway Analysis PFA Models and Probability Map

Description

This submission includes a Na/K geothermometer probability greater than 200 deg C map, as well as two play fairway analysis (PFA) models. The probability map acts as a composite risk segment for the PFA models. The PFA models differ in their application of magnetotelluric conductors as composite risk segments. These PFA models map out the geothermal potential in the region of SE Great Basin, Utah.

57 This is the probability of the Na.K geothermometer being greater than 200 degrees C. This was calculated using simple probability kriging on a composite water chemistry dataset with charge balances no more than +- 5.0 from 0.0. This was used in the heat composite risk segment for play fairway analysis models created in the Structurally Controlled Geothermal Systems, Eastern Great Basin Extensional Regime, Utah, project. The data were derived from the Utah Geological Survey and the Nevada Bureau of Mines and Geology. https://gdr.openei.org/files/643/SE_Great_Basin_Na_K_Geothermometer_Probability%20%281%29.zip
57 This is a play fairway analysis model of the southeastern Great Basin created using a heat composite risk segment (CRS) layer consisting of Na/K geothermometers (probability > 200 degrees C), Quaternary mafic igneous activity (2 km buffer), Quaternary felsic igneous activity (2 km buffer), magnetotelluric conductors (probability >=0.1 S/m), and heat flow (probability >= 80 mW/m squared) and a permeability composite risk segment layer consisting of Quaternary fault density (probability >= 0.5 km length/area, search radius of 5 km, cell size 1 km), Quaternary fault critical stress (3 km diameter circular boundary) and east trending, igneous activity controlling, lineaments (5 km boundaries), and magnetotelluric conductors (probability >=0.1 S/m. Weighting for the model was as follows:Heat composite risk segment = 0.65 and permeability composite risk segment = 0.35. https://gdr.openei.org/files/643/SE_Great_Basin_PFA_Model_1%20%281%29.zip
