Porphyry Cu-Au deposits, polymetallic replacement deposits, and sedimentary rockhosted Au deposits occur in close spatial, and possibly genetic, relationship to the Late Cretaceous arc rocks. A key contribution of this study is the detailed reconstruction of later Cenozoic fault movements that led to structural dislocation and oroclinal bending ...
Using gold-polymetallic deposits in the Edongnan region of China as a case study, stream sediment samples containing concentrations of 39 elements were collected and preprocessed using a centered log-ratio transformation, addressing the closure effect of compositional data. ... Complex interactions between geological …
These gold-bearing, polymetallic veins are predominantly east–west-trending, steeply dipping, discordant calcite-quartz vein systems that formed close to the time of crystallization (within ~15 m.y., based on Pb-Pb ages) of the Nipissing diabase. The ore mineralogy is complex in character, typically comprising sulfides, arsenides, native ...
The Challenger gold deposit in South Australia is hosted by pelitic migmatites that underwent peak metamorphism at ~7.5 ± 1.5 kbars and at least 800°C. Nd model ages suggest a protolith age of ~2900 Ma. Zircon U-Pb and garnet Sm-Nd dating indicates that peak metamorphism occurred at ~2440 Ma and that garnet was present …
The NICO and Sue-Dianne deposits are being explored and delineated by Fortune Minerals Limited in the Mazenod Lake District of the Northwest Territories, using an Olympic Dam model. The deposits were discovered in the south part of the Great Bear magmatic zone (GBMZ) within the Proterozoic, Bear Structural Province of the Canadian …
They are classified either as simple Sb-deposits, where the primary ore is a stibnite mineral, or complex polymetallic deposits with varying contents that include antimony minerals. ... Christidis, C. Orogenic mineralizations—A new exploration target for gold-polymetallic ore deposits in Greece. In Proceedings of the 6th International ...
The relationship between the intrusive complex and the orebody was related to faulting; we infer that the Bianjiadayuan Pb–Zn polymetallic deposit is mainly related to Late Jurassic–Early Cretaceous (144–129 Ma) magmatic activity, and it represents large-scale mineralisation in the context of Paleo-Pacific plate subduction and regional ...
The Pulang giant porphyry Cu-Mo polymetallic deposit is located in the Zhongdian area in the center of the Sanjiang Tethys tectonic domain, which was formed by the westward subduction of the Garze-Litang oceanic slab beneath the Zhongza massif.
