Abstract

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. This map is the first in a series of three showing the uranium content of Australian igneous rocks. Map 1 shows the individual geochemical data points compiled for this study. Points are coloured and sized based on their uranium content. Igneous rock types from Geoscience Australia's 1:1,000,000 national surface geology dataset are also shown in the background. Geochemical analyses from igneous rock types spanning all compositions have been utilised, despite the low total abundance of uranium in ultramafic, mafic and intermediate compositions. 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.
