Abstract

Airborne magnetic surveys provide a cost effective, quick and accurate way to map the subsurface distribution of magnetization for large, usually inaccessible, areas. Differences in magnetization of rock units are related with differences in the content of magnetic minerals within rock units (i.e. their magnetic susceptibility) and their remanent magnetization. Assuming that these properties are discernible between the various rock units, magnetic field anomalies could provide valuable information for the texture of lithological units and even be correlated with distinct lithologies. Here, we evaluate a number of edge mapping techniques applied on a part of the magnetic map of Macedonia and Thrace (N. Greece) in order to delineate the edges of the magnetic sources. The magnetic field anomaly which is studied is created by the so called Philippi granitoid. The mappers used comprise functions of the anomaly and its derivatives. The aimed in locating the lateral limits of subsurface magnetized granitoid.
