This dataset contains interpreted geological data, using combined interpretations of airborne magnetic, radiometric and gravity survey data, mapped at 1:250,000 of deeply buried geological units. In this layer units, along with their associated linework, have been classified as 'deep' since they reside beneath other geophysically interpreted units which are usually themselves below the mapped surface geology. 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occurs in the following areas: St Arnaud 7524, Dunolly 7624, Charlton 7525, Wedderburn 7625 and part of Ararat 7423 are superseded by St Arnaud SJ54-4. Bendigo 7724, Heathcote 7824 and Nagambie 7924 are superseded by Bendigo SJ55-1.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 geological polygons and boundaries, structural lines, miscellaneous lines and metamorphism.
