Metallogenic potential and prospecting of orogenic gold deposits in the Shuihouling area of the Dabie Orogenic Belt: A geochemical evidence from stream sediment anomalies

Solid Earth Sciences
The Shuihouling ductile shear zone, located in the core of the Dabie Orogenic Belt spanning Anhui and Hubei provinces, is a key structural unit with notable mineral potential. Situated within the Wudang-Tongbai-Dabie Mo-REE-Au-Ag-Pb-Zn polymetallic belt,

3D gravity modelling of the Aguablanca Stock, tectonic control and emplacement of a Variscan gabbronorite bearing a Ni–Cu–PGE ore, SW Iberia [PDF]

, 2008
The Aguablanca stock is a Variscan mafic pluton located in the Ossa-Morena zone, southern Iberian Massif, hosting an unusual Ni–Cu–PGE mineralization associated with magmatic breccia pipes which intruded its northern part.

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.

The gold conveyor belt: Large-scale gold mobility in an active orogen

Ore Geology Reviews, 2014
The Southern Alps of New Zealand are part of an active collisional orogen where metamorphism, hydrothermal fluid flow and the formation of orogenic gold deposits are ongoing. The Southern Alps are forming due to transpressional collision between continental crust fragments on the Pacific and Australian tectonic plates.

Alteration Alteration, Mineralization and Geochemistry of Metamorphic Rocks Hosted Hydrothermal Gold Deposit at Rumbia Mountains, Bombana Regency, Southeast Sulawesi, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
In Indonesia, gold is commonly mined from porphyry, epithermal and skarn type deposits that are commonly found in volcanic/magmatic belts. However, were recently numerous gold prospects discovered in association with metamorphic rocks.

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-
