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 ...

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‐

Gold mineralization of the Arctic Belt of the Russian Far East

Руды и металлы
The gold ore-bearing potential of the Early Cretaceous Arctic orogenic belt of the Far Eastern Arctic is characterized. The gold mineralization is represented by the Au-quartz vein, Au-sulfide disseminated in folded and crushed zones, Au-Bi (gold-rare ...

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.

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

Basin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Geographic Patterns of Intra‐ and Interspecific Diversity of Riverine Fish Species in the Italian Northern Apennines and Ligurian Alps

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the suitability of environmental DNA (eDNA) metabarcoding to identify inter‐ and intraspecific diversity patterns of riverine fish populations across the Adriatic and Ligurian drainage basins in Northern Italy. Our results revealed genetic as well as community differentiations, with the Adriatic side displaying higher taxon richness ...
