Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb

Finite Element Modelling of Synthetic Normal Resistivity Logging Tool: Insights Into Vein Parameters, Borehole Fluids and Electrode Configuration

Geophysical Prospecting, Volume 74, Issue 5, June 2026.
ABSTRACT Borehole resistivity logging can play an important role in subsurface exploration by enhancing the accuracy of surface data inversion models. However, its application in the mining industry remains limited due to challenges posed by complex geological formations, particularly in vein‐hosted deposits such as orogenic gold and porphyry copper ...

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

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.

The Impact of Erosion Efficiency on Rift‐Inversion Orogen Evolution: Implications for Serpentinization‐Derived Natural H2 Resources

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Natural hydrogen gas (H2) generated through the serpentinization of mantle rocks is a possible source of clean energy. For efficient serpentinization and large‐scale H2 generation to occur, mantle rocks need to be brought near the surface (exhumed) into a favorable temperature range (the serpentinization window) and in contact with water. Rift‐

Monazite and Xenotime U‐Pb Geochronology and Thermometry of the Blue Ridge and Inner Piedmont of North Carolina: Implications for the Thermal‐Metamorphic Evolution of the Southern Appalachian Metamorphic “Core”

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The southern Appalachian orogen preserves a complex distribution of metamorphism and deformation varying in timing, magnitude, and spatial extent. These complexities give rise to disparate interpretations for southern Appalachian tectonic evolution, which complicates the testing and interpretation of tectonic models in this system.

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.
