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 ...

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.

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.

A review of the current state of knowledge on gold mineralization in Mali, Western Africa

Geology, Ecology, and Landscapes
This paper comprehensively analyses the geology and geochemistry of the relatively understudied gold resources in Mali. It also examines the potential of stable isotopes in enhancing gold prospecting within the Birimian terrane.

Timing and duration of Archean orogenic gold deposits in the Bourlamaque pluton, Val d’Or mining camp, Abitibi, Canada

Ore Geology Reviews, 2020
In the Val-d’Or mining district of the Archean Superior Province, the relationship between regional metamorphism/deformation and the timing of orogenic vein-type gold mineralization is debated; some authors arguing that gold mineralization was coeval ...

Trace-element geochemistry of pyrite and arsenopyrite: ore genetic implications for late Archean orogenic gold deposits in southern India

, 2017
The distribution of Au and associated trace elements in pyrite and arsenopyrite from late Archean Hutti and Hira-Buddini orogenic gold deposits, eastern Dharwar Craton, southern India was investigated by laser ablation-inductively coupled plasma-mass ...

Superimposed Gold Mineralization Events in the Tuanshanbei Orogenic Gold Deposit, Central Jiangnan Orogen, South China

Economic Geology
Abstract The Jiangnan orogen, one of the largest gold-producing areas in China, has experienced multiple orogenic events with complex structural overprinting that is marked by multiple stages of magmatism, deformation, metamorphism, and orogenic gold mineralization.
