AEM Greenland 1994 - Airborne GEOTEM electromagnetic and magnetic survey over Inglefield Land, Greenland

The area for the AEM Greenland 1994 project is located in Inglefield Land, North-West Greenland. The measurements included acquisition of controlled source electromagnetic data (GEOTEM - time domain EM) and total field magnetic data. The survey across the ice-free onshore area (size of 6493 km2) is collected by Geoterrex Ltd. and financed by the Government of Greenland. The main flight lines are oriented north-south and spaced at 400 metres intervals with a set of orthogonal tie-lines at 4000 metre intervals. The area is underlain by an Early Proterozoic (and possibly Archaean) crystalline basement which traditionally has been subdivided into three main units: - Etah group of metasedimentary supracrustal rocks - Etah meta-igneous complex - Variable gneisses The basement is overlain by a succession of younger platform strata (Proterozoic to Cambrian age) in a number of coastal regions
