This Geoscience Australia Record 2001/12 is the result of 'The Metallogeny of Australian Proterozoic Granites' project, undertaken by the then Australian Geological Survey Organisation in collaboration with 20 minerals exploration companies. The project was a data driven exercise that asked the simple question:

'Where hydrothermal Au, Cu, Zn, Pb, Sn, W, and Mo mineralisation occurs within 5 kms of the boundaries of Proterozoic Granites, are there any specific characteristics of either the granites and/or their host rocks?'

The project compiled data on the mineralogy, geochemistry (~7500 analyses), and age of Proterozoic granites and felsic volcanics, as well as the age and mineralogical composition of sediments within 5 kms of Proterozoic granite boundaries for 20 provinces. The project investigated a spatial association only, and hence it was not considered of major importance if the metals came from the granite or had been leached from the country rock by processes related to granite emplacement. Further, the compilation made every effort to focus on factual data. As the determination of the tectonic setting operating at the time of emplacement of the granites, particularly in rocks as old as Proterozoic, was considered to be highly interpretative, this parameter was not included, due to the data-driven approach of the project.

Having compiled the data, a forensic data mining approach was applied. That is, rather than developing a computer derived 'best-fit model' from the data, or taking an existing model and finding areas that matched the prescribed model, a more descriptive approach was tried. Our goal was to investigate the spatial relationship to gain understanding by uncovering patterns and relationships.
