Exploration Activity: Ground Gravity Survey At Coso Geothermal Area (1990)

Exploration Activity Details
Location Coso Geothermal Area
Exploration Technique Ground Gravity Survey
Activity Date 1990

DOE-funding Unknown

 
Exploration Basis
To identify features related to the heat source and to seek possible evidence for an underlying magma chamber
 
Notes
2D and 3D gravity modeling was done using gridded Bouguer gravity data covering a 45 by 45 km region over the Coso geothermal area. Isostatic and terrain corrected Bouguer gravity data for about 1300 gravity stations were obtained from the US Geological Survey. After the data were checked, the gravity values were gridded at 1 km centers for the area of interest centered on the Coso volcanic field. A 3D iterative approach was used to find the thicknesses of both units.
