Statement: This map presents an interpretation of the geology of the Cootamundra 1:250 000 sheet area, based on integration of airborne geophysical data, gravity data and previous geological mapping (Warren, A.Y.E., Gilligan, L.B. and Raphael, N.M., 1996. Cootamundra 1:250 000 Geological Sheet SI/55-11. Second edition. Geological Survey of New South Wales, Sydney. The interpretation was produced with reference to the mapped outcrop geology from the Cootamundra 1:250000 Geology Map (Second Edition 1996). This map should be inspected to gain an understanding of the geological framework used for the geophysical interpretation. The airborne geophysical data were acquired during a survey that was part of the National Geoscience Mapping Accord and jointly funded by AGSO and the Geological Survey of New South Wales. The survey was flown by AGSO alongeast-west lines, 250 metres apart and at a nominal terrain clearance of 80 metres. The interpretation of the data consisted of two phases: Phase 1: Outlining magnetic sources. Phase 2: Correlation of known geology with geophysical responses and the outlining and identification of geological units. The images used for the interpretation and this geophysical interpretation map are available in digital format, suitable for use in most GIS applications.
