On the source of orogenic gold | Geology | GeoScienceWorld
Dec 1, 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), continues largely because it is difficult to reliably identify the source...Read More
Ore genesis - Wikipedia
Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. Ore-genesis theories generally involve three components: source, transport or conduit, and trap. (This also applies to the petroleum...Read More
