Abstract Invisible gold in natural and synthetic arsenian pyrite and marcasite correlates with anomalous As content and Fe deficiency, and high contents of invisible gold in most natural and all synthetic arsenopyrite correlate with excess As and Fe deficiency. As-rich. Fe-de- ficient arsenopyrite synthesized hydrothermally contains up to 3.0 wt% Au uniformly distributed in growth zones of light backscattered electron contrast. At the Deep Star gold deposit, Carlin Trend, Nevada, the sulfide…

Abstract XANES measurements on gold-bearing arsenian pyrite from the Twin Creeks Carlin-type gold deposits show that gold is present as both Au0 and AuI+ and arsenic is present at AsI-. Au0 is
Role of arsenian pyrite in hydrothermal ore deposits: A history and update
Arsenic-bearing pyrite, known as arsenian pyrite, is the most important and in many cases the only Au-bearing mineral in Carlin-type and some epithermal deposits. Because it incorporates Au from
Gold deposition onto arsenian pyrite
Arsenian pyrite is widely known for its dual role as an important host for “invisible” gold in ore deposits, and a major source of arsenic and heavy metal environmental pollution. Despite recent
