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.
