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.

The data displays areas of geological deep leads The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing geology outcrop and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, and placer deposits.

The data contains primary geological data, namely regolith-landform units and boundary types separating regolith-landform units. The dataset is part of the geological mapping dataset, which includes datasets representing geological rock units and boundaries, regolith-landform units and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, metamorphism and placer deposits. The data have been collected by the Geological Survey of Victoria. Data have been captured in projects covering special interest areas, and have been recorded in the field by hand at scales between 1:10,000 and 1:25,000 then prepared for hard copy printing at a range of scales.

This dataset displays areas of contact and regional metamorphism, and the style of metamorphism, mapped using using combined interpretations of airborne magnetic, radiometric and gravity survey data at 1:100,000. At scales larger than 1:120,000 the display is a combination of both 1:100,000 and 1:250,000 geophysical mapping. Recent 1:250,000 geophysical mapping has been of such quality and detail it has been used to supersede older coincident 1:100,000 mapping. This occurs in the following areas: St Arnaud 7524, Dunolly 7624, Charlton 7525, Wedderburn 7625 and part of Ararat 7423 are superseded by St Arnaud SJ54-4. Bendigo 7724, Heathcote 7824 and Nagambie 7924 are superseded by Bendigo SJ55-1. Balmoral 7223, Ararat 7423, Horsham SJ54-3 and St Arnaud SJ54-4 supersede Grampians 7323 where there is overlap. This data has been collected by the Geological Survey of Victoria. This dataset is accompanied by other datasets representing geological polygons and boundaries, sub-surface geological polygons, structural lines and miscellaneous lines.
