Formation of orogenic gold deposits by progressive movement of a fault-fracture mesh through the upper crustal brittle-ductile transition zone. [PDF]

open access: yesSci Rep, 2022
Orogenic gold deposits are comprised of complex quartz vein arrays that form as a result of fluid flow along transcrustal fault zones in active orogenic belts.

The Neglected Involvement of Organic Matter in Forming Large and Rich Hydrothermal Orogenic Gold Deposits

open access: yesGeosciences, 2021
Orogenic gold deposits have provided most of gold to humanity. These deposits were formed by fluids carrying dissolved gold at temperatures of 200–500 °C and at crustal depths of 4–12 km.

Lithosphere architecture characterized by crust-mantle decoupling controls the formation of orogenic gold deposits. [PDF]

open access: yesNatl Sci Rev, 2023
This study, via combined analysis of geophysical and geochemical data, reveals a lithospheric architecture characterized by crust–mantle decoupling and vertical heat-flow conduits that control orogenic gold mineralization in the Ailaoshan gold belt on ...

A review of the characteristics and geological settings of orogenic gold deposits of the Boule Mossi Domain: implication for gold exploration

open access: yesGeology, Ecology, and Landscapes, 2023
This paper reviews the geological characteristics and settings of orogenic gold deposits in the Boule Mossi Domain of West Africa. Understanding the geological characteristics of these deposits is crucial for effective gold exploration in the region ...

Case Histories of Orogenic Gold Deposits

open access: yesMinerals (Basel, Switzerland), 2023
This review compares genetic parameters of 12 orogenic gold deposits. The set of examples is considered to represent largely the variability of orogenic gold deposit (OGD) characteristics. The data are presented in tables and include following definitive

Parameters for the formation of orogenic gold deposits

open access: yesApplied Earth Science: Transactions of the Institute of Mining and Metallurgy, 2019
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 accounting for their formation remain under discussion.

A scale-integrated exploration model for orogenic gold deposits based on a mineral system approach

open access: yesGeoscience Frontiers, 2020
Concept-based orogenic gold exploration requires a scale-integrated approach using a robust mineral system model. Most genetic hypotheses for orogenic gold deposits that involve near-surface or magmatic-hydrothermal fluids are now negated in terms of a ...

Structural geometry of orogenic gold deposits: Implications for exploration of world-class and giant deposits

open access: yesGeoscience Frontiers, 2018
With very few exceptions, orogenic gold deposits formed in subduction-related tectonic settings in accretionary to collisional orogenic belts from Archean to Tertiary times.

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

open access: yesGeochemistry, 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
