Geochemistry and U–Pb Zircon Geochronology of Granite at the Pilok Sn–W Deposit, Thailand: Implications for Late Triassic Tin Metallogenesis

Resource Geology, Volume 76, Issue 1, January/December 2026.
Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

U–Pb dating for zircons from granitic rocks in southwestern Cambodia

Heliyon, 2023
U–Pb dating was conducted for zircons from a total of 14 samples from 13 granite bodies in southwestern Cambodia using LA-ICP-MS. The granitic rock samples were collected from southwestern Cambodia, southwest of the Mae Ping Fault extending from ...

Controls of Base‐Level Cycles on the Sedimentary Architecture of Subaqueous Distributary Channels in a Lacustrine Delta: A Case Study From the Chang 8 Member, Ordos Basin

Geofluids, Volume 2026, Issue 1, 2026.
Base‐level cycles serve as a crucial reference for the stratigraphic sedimentology. In lacustrine basins, high‐frequency base‐level changes contribute to significant diversity and complexity in sequences and sedimentary infilling. The sequences′ infill and facies distribution in lacustrine basins differ greatly from marine deposits.

Influence of Geological Factors on Asphaltene Precipitation From Crude Oils in Tuoputai Area, Tarim Basin, Northwestern China

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Asphaltene precipitation frequently occurs in oil wells within the Tuoputai area of the Tarim Basin, significantly hindering production efficiency. In addition to external factors, such as temperature and pressure, the effects of geological factors on asphaltene precipitation warrant further investigation.

Identifying Framboidal Pyrrhotite: A Proxy for Hydrothermal Alteration of Organic‐Rich Sediments

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Framboidal pyrrhotite, in sharp contrast to framboidal pyrite, has been rarely reported, and its formation remains poorly understood. Here we report its clear identification in a shale‐gas well core and explore its potential as a proxy for diagenesis or low‐grade metamorphism of organic‐rich sediments.

Late Triassic–Early Jurassic paleogeomorphic characteristics and hydrocarbon potential of the Ordos Basin, China, a case of study of the Jiyuan area

Open Geosciences, 2022
Paleogeomorphology is the surface morphology formed by the deposition of strata in the basin in historical period, which is greatly affected by the regional tectonic movement; however, the effect of basin paleogeomorphology on reservoir has been ...

Rock‐buffered versus fluid‐buffered geochemistry of structurally controlled, hydrothermal dolomite: Insights from the Sichuan Basin, China

Sedimentology, Volume 72, Issue 7, Page 2087-2120, December 2025.
ABSTRACT Structurally controlled hydrothermal dolomitization, commonly driven by high‐pressure, high‐temperature fluid–rock reactions, offers insights into the tectonic evolution of sedimentary basins and the geochemical composition of their diagenetic fluids.

Initiation of the Indosinian Orogeny in South China: Evidence for a Permian Magmatic Arc on Hainan Island [PDF]

The Journal of Geology, 2006
Abstract It has been widely accepted that an active continental margin existed along the coast of Southeast China during the Mesozoic time that produced extensive magmatism in the region. However, there is little constraint as to when this active margin was first initiated.

Magmatic System of the Hainan Plume Revealed by Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The magmatic system of the Hainan plume is important for unraveling the mechanism of intraplate volcanism. We develop a detailed three‐dimensional shear‐wave velocity (Vs) model of the crust and uppermost mantle using ambient noise tomography to investigate the magmatic system of the Hainan plume. Rayleigh wave phase velocity dispersions (5–40
