Orogenic gold deposits: part of a global dynamic conjunction between subduction and gold [PDF]

ASEG Extended Abstracts, 2019
Orogenic gold deposits represent a coherent deposit class that were deposited from low-salinity CO2-rich fluids over a range of crustal depths from 3 to 20 km.

The giant Jiaodong gold province: The key to a unified model for orogenic gold deposits?

Geoscience Frontiers, 2016
AbstractAlthough 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 systems, there has been continuing debate on their genesis. Early syngenetic models and hydrothermal models dominated by meteoric fluids are now clearly unacceptable ...

Elemental Geochemical Analysis for the Gold–Antimony Segregation in the Gutaishan Deposit: Insights from Stibnite and Pyrite

Geosciences
In many gold–antimony deposits throughout the world, the sequence of Au and Sb precipitation varies significantly. In high-temperature systems such as hydrothermal Au deposits, gold typically precipitates prior to antimony, whereas in lower-temperature ...

Geology of the Tabakoto gold deposit, Kédougou-Kéniéba Inlier, West African Craton, Mali

BSGF - Earth Sciences Bulletin
The Tabakoto gold deposit is part of the highly endowed west-Malian gold belt, which hosts several world-class deposits. Located in the Paleoproterozoic Kédougou-Kéniéba Inlier (KKI) of the West African Craton (WAC), the deposit is contained in Birimian ...

Primary Controlling Factors of Apatite Trace Element Composition and Implications for Exploration in Orogenic Gold Deposits

Geochemistry, Geophysics, Geosystems
Significant and readily accessible orogenic gold deposits have been previously recognized, exploited, and progressively depleted. Innovative approaches are required to discover new and deeply buried deposits. Recently, trace element variations in apatite
