Exploration Activity: Aeromagnetic Survey At Dixie Valley Geothermal Area (Grauch, 2002)
|Exploration Activity Details|
|Location||Dixie Valley Geothermal Area|
|Exploration Technique||Aeromagnetic Survey|
|Activity Date||2002 - 2002|
This survey was conducted to gain a high resolution magnetic map of the area.
This high resolution aeromagnetic survey covered an area of about 940 km^2. Aeromagnetic data near the range-front fault, which runs through the Dixie Valley Geothermal Area, had to be collected via helicopter due to the extreme topography. Line Spacing was 200 m and ran NW-SE (perpendicular to the range front. Tie lines were made every 1000 m parallel to the regional structures. A Bell Jet Ranger Helicopter carrying a Cesium-vapor magnetometer with a sampling rate of 0.1 seconds was used. The magnetometer was hung from the helicopter at a height of 120 m above the ground. An aeromagnetic map was produced from this survey. The map revealed many faults that were not evident from prior surface exploration.
