Carlin-Type and Low-Sulphidation Epithermal Gold Deposits
... bulk tonnage deposits that are hosted by volcanic rocks. We’ll visit 2 examples of the volcanic-hosted deposits. The first is the Midas Mine, where high-grade gold occurs in veins in basalt-rhyolite (“bimodal”) volcanic rocks. This is one of many vein-type (epithermal) deposits in Nevada. Others of ...

World-class Archean orogenic gold deposits, eastern Yilgarn Craton
... Orogenic gold deposits are generally interpreted to have formed as a result of focussed fluid flow late during active deformation and metamorphism of volcano-plutonic terranes (Groves et al. 1998, Hagemann & Cassidy 2000, Kerrich et al. 2000). Based on relative timing constraints, most authors inter ...

Gold mining
Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth.
