Basins (1:500,000), Geological Interpretation of Geophysical Features Polygon

dataset: GPGEOL500_POLYGON
This dataset contains interpreted geological data, both units underlying the basins and magnetic (mostly volcanic) units enclosed by the basin sediments. The linear features in the data set are geological boundaries, major faults, lesser faults and dykes. The onshore magnetic, radiometric, topographic and gravity data have been collected by the Geological Survey of Victoria. This has been supplemented by offshore magnetic and bathymetric data collected by the Australian Geological Survey Organisation and deep seismic data collected by the Australian Geological Survey Organisation and company sources. The map attempts to reconcile the onshore geology interpreted in Simons & Moore (1999) with the geophysical responses in a way that is geologically reasonable, and to carry this interpretation offshore at least as far as the Tasmanian sea boundary (generally 39 degrees 12 minutes South). The legend broadly uses the same time breaks as that of the Pre-Permian geological map, but includes younger packages that lie beneath the basin. No attempt has been made to subdivide granitic rocks of a particular age. The dataset is accompanied by other datasets representing lava flows and the basin edges. Lava flows have been interpreted either from intersections in drill holes or from magnetic responses. References: MOORE, D.H., 2002.
