Abstract This report summarises the geology and prospectivity of the Wangaratta 1:250 000 map area in northeastern Victoria.
New airborne geophysics conducted over the Wangaratta 1:250 000 map area as part of the Victorian Initiative for Minerals and Petroleum (VIMP) and National Geoscience Mapping Accord (NGMA) programs has enabled a reappraisal of the regional geology and prospectivity of the area. This has been complemented by compilations of mineral resources, mineral exploration and exploration geochemistry.
Broad areas with potential to host a variety of styles of mineralisation have been outlined as a result of this reappraisal. These include:
- Cainozoic placer and supergene gold deposits;
- extensions to and repetitions of historic primary gold deposits;
- thermal aureole gold deposits related to the Strathbogie Granite;
- unrecognised sediment-hosted disseminated gold deposits;
- volcanic-hosted massive sulphide and epithermal gold deposits associated with Cambrian greenstones;
- stratiform base metal-uranium deposits in Upper Devonian–Lower Carboniferous basins and Ordovician Hotham Group;
- tin, molybdenum and gold deposits hosted by granites;
- Cainozoic placer tin deposits;
- diamond deposits;
- Permian coal deposits;
- antimony-gold deposits associated with Upper Devonian calderas;
- porphyry gold-copper-molybdenite deposits associated with high-level intrusions; and
- a variety of industrial minerals.
