Igneous rocks have long been recognised as an important source of metals in uranium mineral systems. Although magmas may form mineral deposits in their own right, they may also contribute directly to basin-related mineral systems as a source of metals and/or ligands. Thus, mapping of the distribution of uranium in igneous rocks has the potential to highlight potentially prospective regions for uranium mineralisation at a macro-scale. Map 2 in the series of three maps of the uranium content of Australian igneous rocks shows polygons of igneous rock distribution, derived from the Geoscience Australia 1:1,000,000 national surface geology dataset. Polygons are coloured by their average uranium content. The average uranium content of each polygon was calculated by plotting the igneous polygons together with geochemical sample points (distribution shown in Map 1 of the series) using ArcGIS software. Each polygon was then attributed with the average uranium value (in ppm) of all intersecting geochemical sample points. This approach allows igneous uranium content to be assessed on the pluton- to province-scale, depending on polygon resolution. Together with the two other maps in the series, this map demonstrates the close spatial relationship between uranium-rich igneous rocks and areas of known uranium mineralisation. In addition, new regions previously unknown for uranium mineralisation can be identified.
