Exploration Activity: Ground Gravity Survey At Raft River Geothermal Area (1957-1961)
|Exploration Activity Details|
|Location||Raft River Geothermal Area|
|Exploration Technique||Ground Gravity Survey|
|Activity Date||1957 - 1961|
From 1957 to 1961 a regional gravity survey was made over the northern part of the Great Salt Lake Desert and adjacent areas in Utah, eastern Nevada, and southeastern Idaho. A total of 1040 stations were taken over an area of about 7000 square miles. The results were compiled as a Bouguer gravity anomaly map with a contour interval of 2 mgal. The Bouguer values ranged from a high of about —120 mgal over the outcrop areas to a low of about —196 mgal over the alluvium-covered graben areas. The gravity high over the Raft River Mountains apparently corresponds with the Raft River Mountains anticline.
