... splay of the Cloncurry fault, which forms a regional tectonic contact with the metasedimentary Corella Formation and is consequently a fundamental structure in the inlier. The deposit has a gangue mineral assemblage of dolomite-calcite-quartz-pyrite (ore type 1) transitional to amphibole-quartz-pyrite...

... system along the regional Cloncurry Fault Zone. Modelling suggests that much of the Cu–Au mineralization is controlled by synthetic R structures associated with this Riedel system. The deformation sequence at Ernest Henry is comparable, but differences in host rock rheology, permeability and fluid...

... and intrusion of the Mount Angelay and Saxby granites. While these hydrothermal breccias are particularly concentrated within the Doherty Formation along the Cloncurry Fault Zone ( Austin and Blenkinsop, 2010 ), the breccias at Brumby appear to be texturally and mineralogically similar and hence are inferred...
