Hyperspectral Imaging At Dixie Valley Geothermal Area (Kennedy-Bowdoin, Et Al., 2003)
Exploration Activity: Hyperspectral Imaging At Dixie Valley Geothermal Area (Kennedy-Bowdoin, Et Al., 2003)
|Exploration Activity Details|
|Location||Dixie Valley Geothermal Area|
|Exploration Technique||Hyperspectral Imaging|
|Activity Date||2003 - 2003|
This Study was conducted to map the location of high temperature hydrothermally altered outcrops.
Mapping of hydrothermally altered mineral outcrops using Hyperspectral analysis was clone in Dixie Valley. The study was conducted vie airborne high resolution hyperspectral imagery. 18 North-South trending flight lines were made with a spatial resolution of about 3 meters. Hydrothermally altered mineral such as alunite, pyrophyllite, and hematite were detected. The analyses revealed several outcrops with these minerals. One large outcrop showed abundant high temperature alteration minerals. The study concluded that the large outcrop has a high probability of recent hot fluid escape.
