Tularosa Basin Play Fairway Analysis: Hydrothermal Alteration Map

Published by University of Utah | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-01-09T00:10:44Z
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.
