Conference Proceedings: Airborne electromagnetic surveys as a reconnaissance technique for geothermal exploration

Abstract
INPUT airborne electromagnetic (AEM) surveys were conducted during 1979 in five Known Geothermal Resource Areas (KGRA's). AEM work has not been significantly utilized in the past for geothermal purposes because it was thought that a shallow exploration technique would not be effective. Extensive audio-magnetotelluric (AMT) work by the USGS in KGRA's showed that many geothermal systems do have a near-surface electrical signature which should be detectable by an AEM system. INPUT responses in the form of nested electromagnetic (EM) profiles and channel ratio maps defined the same conductive zones mapped by AMT in five KGRA's, showing that AEM methods can be useful in exploration for and defining geothermal systems.
