d13C pattern of dissolved inorganic carbon in a small granitic catchment: the Strengbach case study (Vosges mountains, France) [PDF]

, 1999
The transfers and origins of dissolved inorganic carbon DIC. were studied for a year in a soil–spring–stream system in the Strengbach catchment, Vosges mountains, France.

Late Cretaceous to Eocene Sedimentary Source Change and Tectonic Evolution of Nanao Event in Taiwan: Implications From Detrital Zircon U‐Pb Geochronology

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The tectonic evolution of the Taiwan orogenic belt from the Mesozoic to the Cenozoic remains unclear because of a lack of deterministic geochronological data for unraveling stratal sequences. The precise timing of the Nanao event is crucial for uncovering this evolution and is the focus of this study.

Record of Tethyan ocean closure and Indosinian collision along the Ailaoshan suture zone (SW China) [PDF]

, 2015
Zircon U–Pb and Lu–Hf isotopic data along with whole-rock elemental and Sr–Nd isotopic analytical results for the Xin'anzhai and Tongtiange granitic plutons in the Ailaoshan suture zone record the transition from subduction to collision associated with ...

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...

Extreme extension across Seram and Ambon, eastern Indonesia: Evidence for Banda slab rollback [PDF]

, 2013
The island of Seram, which lies in the northern part of the 180°-curved Banda Arc, has previously been interpreted as a fold-and-thrust belt formed during arc-continent collision, which incorporates ophiolites intruded by granites thought to have been ...

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.

Late Jurassic Leucogranites of Macau (SE China): A Record of Crustal Recycling During the Early Yanshanian Orogeny

Frontiers in Earth Science, 2020
The Yanshanian Orogeny consists of Jurassic to Cretaceous compressional-extensional cycles related to the subduction of the Paleo-Pacific Ocean beneath East Asia. Numerous granitic plutons were emplaced across southeast China at distinct intervals over a

Chemistry of Hydrothermally Destabilized Rare-Metal and Radioactive Minerals in Deformed A-Type Granite in the Vicinity of Nugrus Shear Zone, South Eastern Desert, Egypt

Resources
In the Wadi Nugrus area, south Eastern Desert of Egypt, A-type granite is highly deformed in a prominent NW-SE trending shear zone, likely related to the Najd shear system.
