The iron oxide copper-gold (IOCG) group of deposits, initially defined following discovery the giant Olympic Dam Cu-U-Au deposit, has progressively become too-embracing when associated deposits and potential end members or analogs are included. broader includes several low Ti oxide-associated that include (P-rich), (F- REE-rich), Fe Cu-Au skarn, high-grade oxide-hosted Au ± Cu, carbonatite-hosted (Cu-, REE-, F-rich), IOCG sensu stricto deposits. Consideration this broad as a whole obscures...
Mineral deposits represent extraordinary metal concentrations that form by magmatic, magmatic–hydrothermal or hydrothermal processes in geodynamic environments typified anomalously high thermal and/or mechanical energy near plate boundaries. As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend occupy niches. The temporal distributions reflect both formational and preservational processes. In Archaean Palaeoproterozoic, these were...
This study investigates the microstructures, geochemistry, and hydrothermal evolution of gold-bearing pyrite arsenopyrite from six orogenic gold deposits in Archean Eastern Goldfields Province, Western Australia. Scanning electron microscope (SEM), microprobe (EMP) laser ablation-inductively coupled plasma-mass spectroscopy (LA-ICP-MS) analyses show that minerals possess a number similar textural features, including occurrence invisible within initial phases growth, later-stage visible...
Integrated petrological and geochemical examination of metasedimentary assemblages associated with mesothermal lode gold mineralization in five major centers past present production (Ballarat, Percydale, Tarnagulla, Maldon, Fosterville) central Victoria, Australia, reveal that hydrothermal alteration the hosting Cambro-Ordovician turbidites is much more pronounced extensive than has previously been recognized. Characteristically, auriferous reef structures are surrounded by bleached zones up...
New SHRIMP U–Pb data from major felsic intrusives and dykes confirm that initial gold emplacement in the central Victorian province was metamorphic‐related, pre‐dating of Devonian intrusions western Lachlan Fold Belt by as much 80 million years. Importantly, together with previously published geochronological constraints, these strongly suggest no genetic link exists between main phase ‘metamorphism‐related’ orogenic mineralisation magmatism province. A subsequent ‘intrusive‐related’...
This study reports results of mass transfer calculations using chemical modeling software (HCh) to determine parameters that may have had a significant effect on gold deposition in turbidite-hosted Phanerozoic metamorphic terranes. The system modeled was Al-As-Au-C-Ca-Cl-Cu-Fe-H-K-Mg-N-Na-O-S-Sb-Si simulate fluid-rock interaction, gas partitioning, and mineral precipitation veins. Each run takes into consideration both (1) the composition vein fluid minerals predicted precipitate (2) fluids...
Abstract The Lachlan orogen developed as a classic accretionary in an oceanic setting between the palaeo-Pacific subduction zone and Australian craton. Direct evidence for composition age of lower crust basement to thick Palaeozoic turbidite fan is limited. Exposures Cambrian metavolcanic rocks geophysical data suggest that most mafic along with possible small fragments older continental crust. trace element compositions western central are similar those volcanic formed modern back-arc...
