Magnetic/radiometric paralithology of some New England (Australia) granitoids

Abstract

Surveys carried out for the NSW Department of Mineral Resources by Geoex and Geometrics during 1981 have provided digital aeromagnetic and radiometric coverage of the New England region between latitudes 29 and 32° S. The Inverell, Grafton?Maclean, Manilla, Dorrigo?Coffs Harbour, Tamworth and Hastings 1:250 000 sheet areas were flown. All the aeromagnetic data have been processed (IGRF removed, gridded and machine plotted) (Figs 1?3). To date only the Dorrigo?Coffs Harbour 1:250 000 sheet radiometric data have been processed.
