Submarine geohazards on the northwestern continental margin of the South China Sea and their mechanism

Geological Journal, Volume 59, Issue 6, Page 1759-1773, June 2024.
In this paper, we have identified two types of submarine geohazards: direct geohazards and indirect geohazards on the northwestern continental slope and Xisha Uplift of the South China Sea. We conclude the formation of submarine geohazards is constrained by multiple factors, such as tectonic activity, sediment supply and relative changes in sea level ...

Recurrent failure of the continental slope as a key factor controlling reservoir potential in the South China Sea (Qiongdongnan Basin, South Hainan Island) [PDF]

, 2015
High-resolution multi-beam bathymetry, 3D and 2D seismic reflection profiles from the South China Sea are used to investigate the morphology, characteristics, origin and implications to petroleum systems of recurrent slope failure in the Qiongdongnan ...

Methanogenic Archaea as Catalysts for Magnetite Formation in Iron‐Rich Marine Sediments

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 6, June 2024.
Abstract Fine‐grained authigenic magnetite has been recognized increasingly in iron‐rich marine environments affected by methane seepage and is a major sedimentary magnetization source. However, it is unknown whether this magnetite forms via microbial or abiotic processes.

Architecture and evolution of shelf‐margin clinoforms developed in a back‐arc tectonic setting: Insights from quantitative analysis on the south‐west shelf margin of the Ulleung Basin

Basin Research, Volume 36, Issue 2, March–April 2024.
Stratigraphic chart for the Ulleung Basin shows seismic units, eustatic changes, calculated sediment supply and measured shelf‐margin aggradation, with major tectonic events. Brief depositional models of three different seismic units imply the transitional changes from the opening to the closing in the ‘old’ back‐arc Ulleung Basin. Abstract Geophysical

Formation Mechanism of Granitic Basement Reservoir Linked to Felsic Minerals and Tectonic Stress in the Qiongdongnan Basin, South China Sea

Minerals
Recent exploration efforts in the Qiongdongnan Basin have revealed hydrocarbon resources within granitic basement rocks in buried hill traps. However, the formation mechanisms and primary controlling factors of these reservoirs remain poorly understood ...

A Critical Appraisal of the Sensitivity of Detrital Zircon U–Pb Provenance Data to Constrain Drainage Network Evolution in Southeast Tibet

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 2, February 2024.
Abstract Provenance tools, particularly detrital zircon U–Pb analysis, have been widely employed to test drainage network evolution in southeast Tibet and its linkage with the growth of the Tibetan Plateau. Numerous provenance studies have been conducted on the sediments in the paleo‐Yangtze and paleo‐Red River drainage basins.

Genesis of Miocene litho-stratigraphic trap and hydrocarbon accumulation in the Qiongdongnan Basin, northern South China Sea

Geoscience Letters, 2018
In recent years, several large gas fields have been discovered in western Qiongdongnan Basin. It is important and necessary to illustrate their sedimentary characteristics and hydrocarbon migration so that more gas fields could be discovered in the ...

Coupling Relationship between Multistage Fluid Activity and Reservoir Abnormally High-Porosity Zones in the Songtao–Baodao Region, Qiongdongnan Basin

Geofluids, 2021
An abnormally high-porosity zone (AHPZ) is beneficial for petroleum exploration, especially for the deep tight reservoirs in a petroliferous basin. Because of lacking effective research methods, it is hard to analyze the formation process of AHPZs in ...
