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 …

The continuum model has been one of the more widely advocated genetic models for 'gold-
only'deposits such as those found in Archaean greenstone belts. It postulates that …

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 …

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

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 …

Understanding the source of metamorphic sulfur is critical to clarifying the complete cycle of
ore genesis, from source to sink, for several mineral deposit types. In this study, a mass …

The Daqiao gold deposit is hosted in organic-rich Triassic pumpellyite-actinolite facies
metamorphosed turbidites in the West Qinling orogen, central China. Gold mineralization is …

Abstract Concept-based orogenic gold exploration requires a scale-integrated approach
using a robust mineral system model. Most genetic hypotheses for orogenic gold deposits …
