Remote sensing study in support of mineral resource appraisal of the Sewemup Mesa Wilderness Study Area, Mesa and Montrose Counties, Colorado

Abstract

A remote sensing study of the Sewemup Mesa Wilderness Study Area was based on Landsat 2 Multispectral Scanner imagery. These data were processed and analyzed for lineaments and for limonite anomalies that might relate to hydrothermal alteration, migrating hydrocarbons, or uranium. From the lineament analysis, no major basement faults are interpreted. No limonite anomalies of interest are apparent in the imagery, but the narrow outcrop widths compared with the image resolution suggest that any such anomalies probably would go undetected.
