On the source of orogenic gold | Geology | GeoScienceWorld

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), continues largely because it is difficult to reliably identify the source of gold.In this issue of Geology, Gaboury.Stable Isotope and Fluid Inclusion Constraints on the,,The δ 18 O fluid values of the post-ore-stage vein calcite (15.2–21.3‰) are much higher than both the pre- and syn-ore stages. The vapor phase of inclusions contains H 2 S, CH 4, and C 2 H 6 in the syn-ore stages. All these observations reveal that (1) the formation of the Cu skarn deposit was dominated by a magmatic hydrothermal system,Sources of ore-forming fluids and metallic materials in,,This paper presents gas compositions and H-, O-isotope compositions of sulfide- and quartz-hosted fluid inclusions, and S-, Pb-isotope compositions of sulfide separates collected from the principal Stage 2 ores in Veins 3 and 210 of the Jinwozi lode gold deposit, eastern Tianshan Mountains of China.
