Abstract: Use of Earth Resources Technology Satellite: Aeromagnetic, Gravity, and Thermal Data for Mapping Potential Geothermal Resources

L. K. Lepley, A. K. Doss

To delineate areas of state-owned land in southern Arizona for designation as potentially valuable geothermal areas, we analyzed, in combination, registered map overlays of (1) selected lineations from ERTS photographs, (2) Previous HitBouguerTop gravity contours, (3) aeromagnetic residual contours, (4) geology, and (5) subsurface thermal contours. ERTS linears believed to represent Quaternary faults were used to define boundaries of geothermal reservoirs. The highest subsurface thermal gradients were found in wells on the downthrown side of the faults, near intersections of the lineaments, and near recent volcanic or igneous activity. Other geophysical anomalies sought were gravity lows and steep gradients, and sharp magnetic highs or lows.
