Exploration Activity: Hyperspectral Imaging At Dixie Valley Geothermal Area (Nash & D., 1997)
|Exploration Activity Details|
|Location||Dixie Valley Geothermal Area|

|Activity Date||1996 - 1997|
The objective of this study was to determine if Geobotanical anomalies exist over the Dixie Valley hydrothermal convection system, and if so, are they related with soil geochemical, vegetal-spectral, soil spectral, and biogeochemical anomalies. Other goals of this study were to test airborne hyperspectral data for geobotanical anomaly detection and to build a GIS database for hydrothermal convection system characterization.
Vegetal-spectral data, biogeochemical data, and soil-geochemical data was collected in Dixie Valley and Cove Fort-Sulphurdale, Utah. This study aimed to find details about geobotanical anomalies associated with hydrothermal convection systems and mineral deposits. Vegetation and soil was spectrally analyzed at Dixie Valley during ground based field work with a hand held spectrometer. The plants analyzed were Black greasewood. The data collected from the field work was used for ground truth interpretation of airborne hyperspectral imagery. A GIS database was then created with the soil and gas data, soil geochemical data, faults, biochemical data, Landsat Thematic Mapper imagery, roads, townships, and ranges.
