Mining revival [PDF]

, 2010
In relation to its size the United Kingdom (UK) is remarkably well-endowed with mineral resources as a result of its complex geological history. Their extraction and use have played an important role in the development of the UK economy over many years ...

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.

Modeling singular mineralization processes due to fluid pressure fluctuations [PDF]

, 2020
Mineralization in the Earth's crust can be regarded as a singular process resulting in large amounts of mass accumulation and element enrichment over short time or space scales. The elemental concentrations modeled by fractals and multifractals show self-

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 ...

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
