A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

Formation Age and its Geological Significance of Quartz Diorite from Cryptoexplosive Breccia in Dalucao Rare Earth Mine, Sichuan Province

Kuangchan zonghe liyong
To limit the diagenetic age of quartz diorite in the crypto-explosion breccia of the Dechang Dalucao in Sichuan Province, LA-ICP-MS zircon U-Pb chronology was carried out.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Provenance of Middle Triassic sediments in the Southern Youjiang Basin: Insights from detrital zircon geochronology and tourmaline geochemistry

The Depositional Record, Volume 12, Issue 4, September 2026.
Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Trace elements and melt inclusion in zircon within the Qunji porphyry Cu deposit: Application to the metallogenic potential of the reduced magma-hydrothermal system

Open Geosciences
The Qunji porphyry copper (Cu) deposit, located within the Awulale metallogenic belt (AMB) in the western Tianshan orogenic belt, exhibits distinct geochemical and mineralogical characteristics that have not been fully understood.
