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

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

Investigation of Macro‐Meso Mechanical Properties of Cemented Hydrate‐Bearing Sandy Sediments in the South China Sea Using Discrete Element Method

Energy Science &Engineering, Volume 13, Issue 5, Page 2491-2511, May 2025.
ABSTRACT Sandy hydrate reservoirs are considered an ideal target for the extraction of marine natural gas hydrates (NGH). However, engineering geological risks, including reservoir sand production and seabed subsidence during the extraction process, present a significant challenge. In 2019, China discovered a high‐concentration sandy NGH reservoir with

Spatial Heterogeneity of Plant‐Level CCUS Investment Decisions in China's Cement Industry Under Various Policy Incentives

Earth's Future, Volume 13, Issue 3, March 2025.
Abstract Carbon Capture, Utilization, and Storage (CCUS) is widely regarded as a critical technology for achieving deep decarbonization in the cement industry. However, limited research has focused on its plant‐level CCUS investment decisions, especially considering geographic heterogeneity based on the national source‐sink matching optimization.

A database of detrital zircon U–Pb ages and Lu–Hf isotope of sediments in the South China Sea

Geoscience Data Journal, Volume 11, Issue 4, Page 433-442, October 2024.
We mainly collect published detrital zircon of Cenozoic sediments in the South China Sea (SCS, include Hainan and Taiwan Islands). A total of 21,760 detrital zircon U–Pb data from 293 samples and 995 detrital zircon Lu–Hf isotope data from 22 samples were collected in this dataset, with the main age group of the SCS Cenozoic sediments were at 130–95 Ma,
