Tularosa Basin Play Fairway Analysis: Hydrothermal Alteration Map

Published by University of Utah | Department of Energy | Catalog Last Checked: August 03, 2026 at 12:58 AM | Dataset Last Updated: January 09, 2020 at 12:10 AM
This is a hydrothermal alteration map of the Tularosa Basin area, New Mexico and Texas that was created using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) multispectral data band ratios based upon diagnostic features of clay, calcite, silica, gypsum, ferric iron, and ferrous iron. Mesoproterozoic granite in the San Andreas Range often appeared altered, but this may be from clays produced by weathering or, locally, by hydrothermal alteration. However, no field checking was done.
