Ground Gravity Survey At Neal Hot Springs Geothermal Area (Colwell, Et Al., 2012)
Exploration Activity: Ground Gravity Survey At Neal Hot Springs Geothermal Area (Colwell, Et Al., 2012)
|Exploration Activity Details|
|Location||Neal Hot Springs Geothermal Area|
|Exploration Technique||Ground Gravity Survey|
|Activity Date||2011 - 2011|
Gravity surveys were conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. These studies were conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London.
In the 2011 field camp three main gravity profiles were done and over 250 stations were recorded. The instrument used was the Scintrex CG-5. Gravity data was reduced with a 2.20 kg/m^3 Bouguer slab and a nearby absolute gravity benchmark was tied in. Gravity data indicated a high density region in-between lower density regions to the east and west. The high density region correlates volcanic rocks near the surface.
