Exploration Basis
The purpose of the survey was: (1) to field test U.S. Geological Survey extra-low-frequency (ELF) equipment using a grounded wire source and receiver loop configuration (which is designed to measure the vertical magnetic field (Hz) at the loop center for various frequencies); (2) to present an example of the EM sounding data and interpretations using a previously developed inversion program; and (3) to compare graphically the EM results with previously reported DC Schlumberger results for a geothermal environment.
 
Notes
Five ELF frequency soundings were made using a grounded wire source with a minimum length of 1480 meters and a maximum length of 3057 meters. The maximum frequency range for each sounding was from 1 hertz to 2000 hertz.
