Abstract The use of detrital rutile as an indicator of mineralisation is contingent on the identification of trace element signatures that uniquely distinguish rutile grains derived from mineralisation from those sourced from barren rocks. In order to discriminate rutile sources, principal component analysis was applied to a total of 3149 LA-ICP-MS analyses of rutile from ore environments (Au, Au-Cu, pegmatites, carbonatites, lamprophyres, VHMS) and barren igneous and metamorphic rocks. Hierarch...

Abstract The Teutonic Bore Camp, comprised of the Teutonic Bore, Jaguar and Bentley deposits, is one of the most significant volcanic-hosted massive sulphide (VHMS) camps in Western Australia. Despite being extensively studied, only recently there have been advances in the understanding of the mechanism that drove the formation of mineralisation. It has been recognized by recent studies that the volcanic-hosted deposits from the Teutonic Bore Camp represent replacement-type VHMS systems, with si...

Abstract Iron formation-bearing sequences from the Guanhaes Tectonic Block and Southern Espinhaco Belt of the Southeastern Sao Francisco Craton, were affected by the Ediacaran-Cambrian Brasilian Orogeny, when the Guanhaes Block was upthrusted onto Statherian metasedimentary units of the Lower Espinhaco Supergroup. The iron formation contain a number of hydrothermal high-grade iron ore bodies (e.g. Horto-Baratinha, Cuite, Morro Escuro and Morro do Pilar deposits). Three different types of zircons...

Abstract Sulfide Cu isotope systematics have been used as a metallogenic tracer in various deposits; however, only rarely in magmatic Ni-Cu sulfide deposits. Here we present chalcopyrite δ34S and δ65Cu data for the Kalatongke and Baishiquan Ni-Cu sulfide deposits in the Central Asian Orogenic Belt. The Kalatongke deposit yields δ34S of -3.99 ‰ to 3.30 ‰ and δ65Cu of -1.32 ‰ to 0.07 ‰, whereas chalcopyrite from the Baishiquan deposit has δ34S values ranging from 1.70 ‰ to 4.98 ‰ and δ65Cu from -0...

Abstract The medium-sized Zixi gold deposit is hosted in a meta-gabbro–diabase dike, and located geologically in the Xuefengshan belt of the Jiangnan Orogen in South China. Gold-bearing quartz–carbonate–sulfide veins and the ore-hosting meta-gabbro–diabase dike are structurally controlled by the NE-trending F1 faults, which are secondary faults to the regional Xupu–Jingzhou Fault. Metallic minerals at Zixi include arsenopyrite and pyrite, along with minor chalcopyrite, sphalerite, galena, bourno...

Abstract The middle–late Mesozoic tectonic evolution of the South China Block is not well constrained due to limited studies of synchronous mafic rocks in this area. The Dengfuxian area is located at the central to northern parts of the Nanling Range in the South China Block with many lamprophyre dikes seen cross-cutting the late Jurassic granites. This contribution is the first to report the whole-rock geochemistry, zircon U–Pb age and Sr–Nd–Hf isotope signature of these lamprophyres; provide a...
