This dataset contains primary geological data, namely outcropping/sub-cropping geological rock units. This layer has been superseded by the Seamless Geology layer - SG_GEOLOGICAL_UNIT_250K The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing structural lines, miscellaneous lines, miscellaneous polygons, metamorphism, and placer deposits.

This dataset contains primary geological data, namely Pre-Permian geological rock units and boundary types separating rock units. The linear features in this dataset are only comprised of geological boundaries and faults. The data has been collected by the Geological Survey of Victoria. This dataset is accompanied by another dataset representing metamorphism. The pre-Permian geology data from Simons and Moore (1999) shows the interpreted geology of Victoria, with the Permian and younger units stripped off. It was compiled from the surface geology map and interpretation of the extensive new magnetic, radiometric and gravity data along with seismic profiles where available. It attempts to reconcile the mapped geology with the geophysical data sets, to produce a map that is both geologically and geophysically reasonable. The data should be used in combination with the state magnetic image as this image gives extra information that could not be adequately presented on the map, such as sedimentary or contact-metamorphic changes in the magnetic properties of rock packages, dyke swarms, and thick basalt cover. The legend subdivides the rocks by time and palaeoenvironment or geochemistry, which gives a complementary view of the geology to that of the surface Australian crust during Phanerozoic orogenic events. Granites were subdivided using White and Chappell's (1983) S, I and A classification, as this is a subdivision that is both generally understood and works well with the magnetic data. The time subdivisions are at the natural breaks in the Victorian geological record, usually the ends of orogenies. This has meant that all the intrusions associated with a particular event are grouped in the same time slice, even when some could perhaps be allocated to a younger time slice.

The data contains primary geological data, namely outcropping/sub-cropping geological rock units. This layer has been superseded by the Seamless Geology layer - SG_GEOLOGICAL_UNIT_50K The dataset is part of the geological mapping dataset, which includes datasets representing geological rock 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 typically been captured in projects covering 1:100,000 mapsheets, and have typically been recorded in the field by hand at 1:25,000 then prepared for hard copy printing at 1:50,000.

This dataset contains interpreted geological data, using combined interpretations of airborne magnetic, radiometric and gravity survey data, mapped 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 sub-surface geological polygons, structural lines, miscellaneous lines and metamorphism.

The Ouyen SI54-15 and Horsham SJ54-3 map areas are datasets derived from a combination of Geological Interpretation of Basement Geophysical Features maps and Geological Interpretation of Post-Cratonic Geophysical Features maps performed by Moore, D. H. This data has been collected by the Geological Survey of Victoria. This dataset is accompanied by other datasets representing sub-surface geological polygons, structural lines, miscellaneous lines and metamorphism.

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.
