Geophysical interpretation of the Braidwood Granodiorite on the Braidwood 1:100 000 sheet

Abstract

Interpretation based on the Total Magnetic Intensity (TMI), gravity, radiometric and digital elevation data acquired as a part of the Exploration NSW initiative, focused on the northern part of the Braidwood Granodiorite and its extension to the north of the Shoalhaven River. The use of image processing Sobel filters on the TMI gridded data enhance characteristics such as faults and regional stress fields that would otherwise be very difficult to observe.
