f Transient airborne EM applied to geological mapping

GEOTEM is a high performance time domain airborne EM (AEM) system developed for mineral exploration and geological mapping applications. The historical focus for transient AEM has been on direct detection of massive sulfide type targets or other mineralized zones which have intrinsically high electrical conductivity. A bi-product of airborne EM surveys, particularly transient airborne EM surveys, has been a wealth of data which has considerable potential for mapping geology but which has seen limited use. With the advent of high quality digital GEOTEM data, new applications are being addressed.
