The Curnamona Province is the southern remnant of the Palaeoproterozoic Pb-Zn belt, and represents but a small fragment of the original superbasin. Geological data supports the idea of the basin being a rift, with sediments in the Broken Hill Domain being deposited in the rift axis, and the Olary Domain representing the western shelf. The publication by Conor and Preiss (2008) titled ‘Understanding the 1720–1640 Ma Palaeoproterozoic Willyama Supergroup, Curnamona Province, Southeastern Australia: Implications for tectonics, basin evolution and ore genesis’ provides a reasonably up-to-date understanding of the geology of the Southern Curnamona Province, of which the Olary Domain is a part. Therefore participants on this field excursion, who are not familiar with the geology of the region, are referred to this paper. Additionally, the paper includes an extensive reference list. The oldest rocks of the region are exposed in the Willyama Inliers, which were delineated by Neoproterozoic graben formation, and deformed by the Cambrian Delamerian Orogeny. The two inliers that will be visited are the Bimbowrie and Walparuta Inliers. During the two field days it is hoped to provide information about, and examples of, the following aspects of the geology of the Olary Domain: 1. Introduction to the stratigraphy of the Willyama Supergroup in the Olary Domain, and variation relative to the Broken Hill Domain; 2. Regional morphology of the southern Curnamona Province and outcrop patterning; 3. Syn-Willyama magmatism (~1718 Ma Abminga Subsuite and ~1711 Ma Ameroo Subsuite of the Basso Suite, Montstephen Metabasalt, ~1685 Ma Lady Louise Suite); 4. Growth faulting, and onlap; 5. Structures of the Olarian Orogeny; 6. Exhalites and related mineralisation (Cu-Au); and 7. Breccia-controlled Cu-Au (Fe-Ba) mineralisation and related Mesoproterozoic granite.
