摘要: Abstract We use remote sensing data from a variety of satellite and airborne instruments to characterize mineral thermal properties as surface indicators geothermal resources in Nevada. generally reconnaissance tool target higher resolution collections. Spectral are collected field locations samples validate identifications refine maps. validation is done using an ASD portable spectrometer (0.4–2.5 μm) both lab configurations. also have Thermo/Nicolet Nexus 6700 FTIR shared Designs Prototypes instrument for infrared collection. Past work has identified sinter, tufa, travertine, argillic hydrothermal alteration minerals, evaporites, vegetation concentration near springs, anomalies indicative resource potential structural controls on fluid pathways. Our methodology places maps into GIS databases with other geologic information make comparisons site assessments. recommend areas subsequent exploration including shallow temperature measurements, detailed mapping, analyses. This paper reviews over decade Nevada summarizes the common unique features by our surveys.
