Orogenic gold deposits of all ages, from Paleoarchean to Tertiary, show consistency in
chemical composition. They are the products of aqueous-carbonic fluids, with typically 5–20 …

Pyrite is one of the most common minerals in many precious and base metal hydrothermal
ore deposits and is an important host to a range of trace elements including Au and Co and …

The term orogenic gold deposits has been widely accepted, but there has been continuing
debate on their genesis. Early syn-sedimentary or syn-volcanic models and hydrothermal …

Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

Formation of hydrothermal ore deposits requires a fluid with the capability to transport and
deposit metals, and the sources and physical and chemical characteristics of these …

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 …

A metamorphic devolatilization model can explain the enrichment, segregation, timing,
distribution and character of many goldfields such as those found in Archean greenstone …

A comprehensive account of ore-forming processes, revised and updated The revised
second edition of Introduction to Ore-Forming Processes offers a guide to the multiplicity of …

Although the term orogenic gold deposit has been widely accepted for all gold-only lode-
gold deposits, with the exception of Carlin-type deposits and rare intrusion-related gold …

Metamorphic belts are complex regions where accretion or collision has added to, or
thickened, continental crust. Gold-rich deposits can be formed at all stages of orogen …
