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‐

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.

Prospectivity analysis of orogenic gold deposits in Saqez-Sardasht Goldfield, Zagros Orogen, Iran [PDF]

Ore Geology Reviews, 2017
Abstract Diverse deposit-types or mineral systems form by diverse geological processes, so translation of knowledge about the controls of mineralization acquired from the 4D geological modeling into 2D spatial predictor maps is a major challenge for prospectivity analysis.

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.

GOLD MINERAL PROSPECTING USING PHASED ARRAY TYPE L-BAND SYNTHETIC APERTURE RADAR (PALSAR) SATELLITE REMOTE SENSING DATA, CENTRAL GOLD BELT, MALAYSIA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
The Bentong-Raub Suture Zone (BRSZ) of Peninsular Malaysia is one of the significant structural zones in Sundaland, Southeast Asia. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai arc in the east. The BRSZ is

Carbon dioxide as a proxy for orogenic gold source

Ore Geology Reviews, 2020
Abstract Despite many decades of study, the genesis of orogenic gold deposits remains in debate. One aspect of this debate concerns the origin of the mineralising fluids. Two important constraints are that the fluids are sulphur and CO2 bearing and that high fluid fluxes are maintained in a spatially localised environment for a relatively short ...

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 ...
