Re-channelization of turbidity currents in South China Sea abyssal plain due to seamounts and ridges [PDF]

, 2021
Turbidity currents can be characterized as net-erosive, net-depositional or net-bypassing. Whether a flow is erosive, depositional or bypasses depends on the flow velocity, concentration and size but these can also be impacted by external controls such ...

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

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.

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

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 ...

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.
