Improvements using modern Airborne Data – A Case Study from NE Libya

High resolution aerogravity and aeromagnetic data were acquired in 2006 over a licence area in NE Libya. These data are compared with ground gravity and vintage magnetic data acquired in the 1960s and 1970s. The improvement with respect to the resolution of the tectonic features is discussed. The new data provided an excellent background for seismic survey planning. An area of about 30 x 80 km was covered with denser infill aerogravity lines (500 m line spacing). These data are investigated in order to test the improvement in resolution due to tighter line spacing as claimed by Sander et al., 2003.
