Exploration Basis
The aim of the resisitivity surveys was to try to identify the location of the geothermal reservoir feeding the hot springs
 
Notes
The Schlumberger soundings involved a transmitting dipole with length ranging from 500-2,500 feet for a 100-foot receiving dipole to 2,500-15,000 feet for a 500-foot receiving dipole. Injected currents of 2-6 amperes were used with a frequency of 0.05 Hz read as an averaged DC-coupled signal by the receiver. All measurements were obtained using a GEOEX Mark 4 induced polarization-resistivity system. Apparent resistivities in the zone ranged from 33-300 ohm-meters, with the lowest readings in synclinal Mesozoic sediments 2-3 km west of Black Sage Pass. Henrichs Geoexploration Company [1981] interpreted this zone as a 50 ohm unit of Mesozoic sediments over a 2000 ohm Precambrian crystalline basement. It should be noted that these surveys were conducted prior to the advent of modern inversion techniques (and computing power) and, as such, a reanalysis of these data may prove fruitful in identifying or better characterizing anomalies potentially associated with geothermal reservoirs.
