Abstract
The Crow Springs mining district in the north-central portion of Esmeralda County is in an unnamed range of low foothills between the Cedar Mountains on the west and the Great Smokey Valley on the east. The older rocks of the area consist of a well exposed porphyritic quartz monzonite, which intruded the Triassic Excelsior Formation. The igneous activity was accompanied by moderate hydrothermal alteration and subsequent erosion has exhumed the quartz monzonite. These events' were followed by extrusion of a series of Tertiary volcanics and Quaternary basalts which lie unconformably on the porphyry and Excelsior Formation and have been faulted generally north-south and tilted to the west.
The area was selected as a site for a remote sensing evaluation because of the excellent exposure of the porphyry, alteration zones and a wide range of rock types and structural features. The almost total absence of vegetation and the very dry desert environment made it ideal to test the ability of airborne sensors to discriminate geologic parameters. Detailed ground-studies related target signatures to airborne sensor systems and were used to establish flight lines and times best suited to accomplish experimental objectives. An analysis of the data from the infrared, microwave, radar and camera systems and their relationships to the physical characteristics of geologic materials is discussed.
