This dataset contains interpreted geological data, using combined interpretations of airborne magnetic, radiometric and gravity survey data, mapped at 1:250,000. 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occurs in the following areas: St Arnaud 7524, Dunolly 7624, Charlton 7525, Wedderburn 7625 and part of Ararat 7423 are superseded by St Arnaud SJ54-4. Bendigo 7724, Heathcote 7824 and Nagambie 7924 are superseded by Bendigo SJ55-1.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. 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 is a pseudocolour image of uranium (U) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher U parts per million (ppm) values. Colour: 2005 uranium Victorian state-wide 50x50m grid. Intensity: 2005 uranium Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.
