Gas Hydrate Occurrence Inferred from Dissolved Cl- Concentrations and delta O-18 Values of Pore Water and Dissolved Sulfate in the Shallow Sediments of the Pockmark Field in Southwestern Xisha Uplift, Northern South China Sea [PDF]
, 2014 Deep-water pockmarks are frequently accompanied by the occurrence of massive gas hydrates in shallow sediments. A decline in pore-water Cl-concentration and rise in delta O-18 value provide compelling evidence for the gas hydrate dissociation.

Geofluids, Volume 2026, Issue 1, 2026.The deep‐water area of the south slope of the Lingshui Depression in the Qiongdongnan Basin has already yielded the Deep Sea No. 1 gas field. However, so far, there have been no significant breakthroughs in exploration in the shallow‐water area of the north slope.

Cryptic Carbon Cycle at Methane‐Seeps of the South China Sea: Evidence From Porewaters
Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.Abstract Anaerobic oxidation of methane (AOM) governs methane consumption at seeps, yet δ13C‐CH4 values in the sulfate‐methane transitions are commonly lower than predicted from preferential 12C utilization by methanotrophic archaea, suggesting the influence of a different methane source. To address this isotope discrepancy, we used high‐resolution ion

Geochemical Characteristics of Natural Gas in the Yinggehai-Qiongdongnan Basin, South China Sea
Energy Exploration & Exploitation, 2010 Geochemical characteristics of natural gas in the Yinggehai-Qiongdongnan Basin were studied and analyzed based on gas component properties and carbon isotopic characteristics which were tested and collected of more than 100 samples. The gas in the Yinggehai-Qiongdongnan Basin was generally alkane gas, and all the area showed dry gas characteristics ...

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
