Research dynamics and frontier trends of orogenic gold deposits: a knowledge map based on bibliometrics

Frontiers in Earth Science
Orogenic gold deposits represent a vital component of global gold reserves, functioning as both significant sources of gold and essential indicators for understanding crustal metallogeny within collisional tectonic environments.

Genesis of Gold Mineralization at Rodruin Prospect, Eastern Desert, Egypt: Evaluating Metamorphic vs. Magmatic Fluid Contributions

Resources
This study investigates the genesis of gold mineralization at the Rodruin prospect in the central Eastern Desert (CED) of Egypt, with the aim of constraining the relative contributions of metamorphic and magmatic fluids to ore formation.

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

Geochemistry, Geophysics, Geosystems
The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in ...

Gold in Ophiolites [PDF]

, 2004
Ophiolites, as a class, have been currently under-estimated as potential gold targets, although they have been the subject of major scientific research. Their resources have also attracted investors producing Cr, Cu (massive sulphides), Co, Ni (laterites)

Primary Au prospecting results in the Logrosán area (Central Iberian Zone, Spain). [PDF]

The Central Iberian Zone presents an exceptional geological interest for its great exploration potential for a number of elements including gold. Metallogeny within the area is mainly related to regional metamorphism and late magmatic activity during the

Geological and S–Pb–He–Ar isotope constraints on the origin of the Muping–Rushan gold belt, Jiaodong Peninsula, eastern China

BSGF - Earth Sciences Bulletin
The Muping–Rushan gold belt is one of three gold mineralization belts in Jiaodong Peninsula, eastern China, comprising between the Sulu ultrahigh-pressure metamorphic belt and North China Craton. This study investigates the source of gold and ore-forming

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
