Structure of the NE Oman Mountains: A Review of Robust Geochronological Constraints for Tectonic Models of Ophiolite Obduction and Continental Subduction

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Late Cretaceous Semail ophiolite, Oman was emplaced onto the previously passive continental margin of Arabia. Recent geochronology from the ophiolite, its metamorphic sole, and associated high‐pressure (HP) metamorphic rocks have resulted in a proliferation of new tectonic models explaining the sequence of events associated with ophiolite ...

Modeling nitrogen loss using stable isotopes in mountainous watersheds of the Bohemian Slavkov Forest (NW Czech Republic)

Vadose Zone Journal, Volume 24, Issue 4, July/August 2025.
Abstract This study presents an integrated hydrological‐hydrochemical approach to quantify reactive nitrogen (NR) cycling in temperate mountain catchments. It employs stable isotope analyses (δ2H, δ18O in water, δ15N in NH4+, and NO3− and δ18O in NO3−) to resolve interactions between water flow and N transformations.

The Tectonic Responses in the Overriding Plate During the Tethyan Convergence and the Progressive Extrusion Process in Sundaland: Insights From the Wuliangshan Massif, SE Tibetan Plateau

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract The overriding plate commonly accumulates less strain than the subducted plate during continental collision. Analyzing plate interactions from the perspective of the overriding plate provides important insights into orogenic dynamics. In the southeastern Tibetan Plateau, the Wuliangshan massif, as a key region of the overriding plate, records ...

Geochronological and geochemical features of magmatic gold- and silverbearing complexes in the Chukotka sector of the Russian Arctic coast

Литосфера, 2020
Research subject. This study was devoted to magmatic complexes in Northwestern Chukotka associated with the largest gold and silver deposits across Kupol’skii (Kupol field) and Ilirnei (Dvoinoe and September fields) ore junctions.

Electron Microprobe Chemical Dating of Uraninite as a Reconnaissance Tool for Leucogranite Geochronology [PDF]

, 2007
We suggest that electron microprobe techniques may be employed to date Tertiary samples of uraninite (UO~2~), which can contain very high concentrations of radiogenic Pb after only a few million of years of U and Th decay. Although uraninite is regarded

Le "cadre géologique" dans l'article de géologie en français et en anglais: crédibilité et retenue sur le terrain [PDF]

, 1998
While the features of the scientific research article have been widely investigated in numerous disciplines over the past 15 years, relatively scant attention has been paid to the important discipline of geology.

Lithospheric Unzipping Explaining Hot Orogenesis During Continental Subduction

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Phanerozoic accretionary orogens typically contain upper crustal nappes derived from subducted lithosphere—oceanic or continental—that display (ultra‐)high‐pressure, low‐temperature ((U)HP‐LT) metamorphism. Surprisingly, such orogens often also contain coeval continent‐derived nappes that underwent “Barrovian” (MP‐HT) syn‐burial metamorphism ...

Structures and Leucogranites in the Eastern Himalayan Orogen From Reprocessed INDEPTH‐I Deep Seismic Reflection Profile

Tectonics, Volume 44, Issue 6, June 2025.
Abstract The INDEPTH‐I seismic reflection transect provides a unique data set for understanding active mountain‐building processes during continental collision in the Himalaya and has played a key role in the development of ductile extrusion and channel flow concepts.

Early Evolution of Himalayan Orogenic Belt and Generation of Middle Eocene Magmatism: Constraint From Haweng Granodiorite Porphyry in the Tethyan Himalaya

Frontiers in Earth Science, 2020
Although the Himalayan orogenic belt is dominant by Oligocene to Miocene leucogranites, it initiated magmatic activity from middle Eocene. However, the exact distribution and genesis of early magmatism are yet to be resolved.
