Abstract
The magnetotelluric method has become widely accepted as a geophysical tool for geothermal exploration. This application is based on the tool's ability to detect electrically conductive zones in the geothermal prospects. This paper will discuss some of the implications derived from magnetotelluric data acquired in the Socorro Peak KGRA, New Mexico, and in the Railroad Valley, Nevada. The magnetotelluric data in Socorro show the response to a shallow (5 km) magma body. The data from Railroad Valley, indicate a classical basin and range, two dimensional boundary response and strong indications of potential geothermal anomalies, even in the presence of the highly two dimesional complex structure.
