Abstract

Aeromagnetic data from the highly structured and metamorphosed geology of the Highland Rocks 1:250 000 map sheet of the Arunta Block of the Northern Territory is virtually impossible to interpret in its original form by virtue of complexity due to the inclination of the Earth’s magnetic field, interference between anomalies, regional effects and an extreme range of anomaly amplitudes. Only by employing a comprehensive suite of enhancement techniques is it possible to produce an interpreted geological map of the area. Although virtually no geological control exists for the area it has been possible delineate lithologic units and a complex system of faults in which thrusting appears to predominate.
