Geology, fluid inclusions, mineral and (S-O) isotope chemistry of the Badran orogenic Au deposit, Yana-Kolyma belt, eastern Siberia: implications for ore genesis

Frontiers in Earth Science
The Badran orogenic gold deposit is located in the Yana-Kolyma belt, Eastern Siberia; it has proven reserves of ∼9.3 t of gold and an average grade of 7.8 ppm. The total gold production at the Badran deposit since 1984 amounts to ∼34 t.

A Database of Low‐Temperature Thermochronology in East Asia

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Spatial distribution of low‐temperature thermochronology samples in East Asia. ABSTRACT The low closure temperature of the dating system in low‐temperature thermochronology allows shallow crustal movements to be recorded. In recent decades, this approach has been used extensively in studies of orogenic belt exhumation, sedimentary basin evolution, and ...

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.

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.

Mineral Prospectivity Prediction in the Mayoumu Area, Tibet, Based on Multi-Source Exploration Information and Ensemble Learning Models

Remote Sensing
Plateau–orogenic belts host a substantial share of global gold resources, yet quantitative prospectivity mapping is challenged by complex mineralization and strongly heterogeneous, multi-scale datasets.

Mayum: an orogenic gold deposit in Tibet, China

Ore Geology Reviews, 2009
Abstract Located in western Tibet, China, the Mayum orogenic gold deposit was discovered in 2002 with estimated resources of > 80 tonnes gold. The gold mineralization is hosted by Neoproterozoic–Cambrian schists, and is controlled by nearly parallel E–W trending bedding-concordant fracture zones.

Coupling deformation and fluid P-V-T-X conditions in orogenic gold deposits

, 2009
Deformation is intimately linked to fluid conditions in fault related ore systems such as orogenic gold deposits. Orogenic gold fluids are characterised by complex CO2-H2O-NaCl fluids with XCO2 values typically between 0.1 and 0.3 and salinities of 3 to ...
