Controls on the Distribution of Invisible and Visible Gold in the Orogenic Gold Deposits of the Yangshan Gold Belt, West Qinling Orogen, China [PDF]
Minerals, 2019 Six orogenic gold deposits constitute the Yangshan gold belt in the West Qinling Orogen. Gold is mostly invisible in solid solution or in the sulfide lattice, with minor visible gold associated with stibnite and in quartz-calcite veins. Detailed textural and trace-element analysis of sulfides in terms of a newly-erected paragenetic sequence for these ...

On the source of orogenic gold [PDF]
Geology, 2013 Gold has historically been a key strategic commodity, and the study of gold deposit formation has long been investigated. Debate on the genesis of so-called “orogenic gold deposits” (>75% of gold recovered through history; [Phillips, 2013][1]), continues largely because it is difficult ...

PROGNOSTIC ESTIMATE OF NOBLEMETAL RESOURCES IN PROMISING ORE DISTRICTS OF THE KARELIAN REGION
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017 The gold and platinoid resources of the Karelian region are expected to increase. Our prediction is based on the leading genetic types of noble-metal mineralization known in the region such as the low-sulphide Pt-Pd type in layered plutons and gabbro ...
