Exploration Basis
An electromagnetic survey was conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. The study was conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London.
 
Notes
In this survey the field camp students set up five 100 X 100 m, 1 dimensional central loop soundings 100 m apart. For one of the fixed loop surveys, measurements were made at 25 m inside the loop and 25 m outside the loop. 15 repetitions were collected at each station. The EM-47 transmitter was used with a bipolar square wave output. The instrument was set up to output a 2 amp current, at a 7.5 Hz repetition rate, and a current ramp off of about 6 micro seconds. The receiver coil had a bandwidth of 270 kHz. The depth penetration of this survey was about 150 m. The survey was centered at the inferred location of the main fault zone.
