Although the term orogenic gold has become widely accepted over the past 20 years for
disseminated-to lode-style gold deposits that formed in a variety of tectonic environments …

The so-calledmesothermal'gold deposits are associated with regionally metamorphosed
terranes of all ages. Ores were formed during compressional to transpressional deformation …

Epigenetic gold deposits in metamorphic terranes include those of the Precambrian shields
(approx 23,000-25,000 t Au), particularly the Late Archean greenstone belts and …

Orogenic gold deposits have formed over more than 3 billion years of Earth's history,
episodically during the Middle Archean to younger Precambrian, and continuously …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

Structurally hosted lode gold-bearing quartz vein systems in metamorphic terranes possess
many characteristics in common, spatially and through time; they constitute a single class of …

Lode gold deposits in Precambrian cratons represent the world's major gold source and
were mostly generated during formation and stabilization of the cratons. However, there is …

Most Archaean gold ores belong to a coherent genetic group of structurally controlled lode-
deposits that are characteristically enriched in Au with variable enrichments in Ag, As, W, Sb …

Orogenic gold deposits are the main source of gold for humanity. These deposits formed
from the Archaean to Phanerozoic at crustal depths of more than 4 km. The key parameters …

There are six distinct classes of gold deposits, each represented by metallogenic provinces,
having 100's to> 1000 tonne gold production. The deposit classes are:(1) orogenic gold;(2) …
