Geology and mineraization in the western Lachlan Fold Belt: Recent studies of the tectonics, stratigraphy and mineralization of the cobar?mineral hill region

Abstract

Studies of the Cobar?Mineral Hill region by the Geological Survey of New South Wales commenced late in 1972, and are planned to continue until at least 1977. Regional mapping has led to a clearer understanding of the stratigraphy. Metallogenic mapping of the Cobar, Nymagee, and Bourke 1:250,000 sheets by the Geological Survey and recent work by exploration and mining companies have resulted in a better appreciation of the controls of mineralization in the Cobar region. However, our understanding is by no means complete, and further advances will depend greatly on a more detailed knowledge of the geology of the region.
