    10.02.2020· Geologists have studied gold deposits for decades and know of different processes that form gold deposits. Klondike gold formed by one of these processes. The gold in the Klondike is known as orogenic gold. The word "orogenic" refers to a mountain-building event. Orogenic gold is gold that formed during a mountain-building event.

    Here, the gold is further concentrated by the action of water. Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be worked using a gold pan or cradle. Alluvial gold deposits ...

    01.04.1998· The so-called `mesothermal' gold deposits occupy a consistent spatial/temporal position (), having formed during deformational processes at convergent plate margins (orogeny) irrespective of whether they are hosted in Archaean or Proterozic greenstone belts or Proterozoic and Phanerozoic sedimentary rock sequences (e.g. Barley and Groves, 1992; Kerrich and Cassidy, 1994).

    It ranks number 56 of the elements in terms of earth crust abundance and number 18 among the metallic elements. A main factor determining the location of tungsten deposits is the proximity to orogenic belts because of a marked association between tungsten deposits and those mountain belts as, for example, in the Alpine-Himalayan and the Circumpacific Belts.

    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.
