Cenozoic tectonic subsidence in the Qiongdongnan Basin, northern South China Sea

Basin Research, 2016
AbstractA number of major controversies exist in the South China Sea, including the timing and pattern of seafloor spreading, the anomalous alternating strike‐slip movement on the Red River Fault, the existence of anomalous post‐rift subsidence and how major submarine canyons have developed.

Source-to-sink system for peat accumulation in marginal basins of the South China Sea with the Qiongdongnan Basin as an example

Australian Journal of Earth Sciences, 2020
In the coal-bearing deposits of the Qiongdongnan Basin in the South China Sea, coal seams are for the most part extremely thin, typically less than 0.5 m.

The formation environment and development modes of Cenozoic source rocks in the Qiongdongnan Basin

Chinese Journal of Geochemistry, 2012
According to the drilling results, there are three sets of source rocks of the Cenozoic Group in the Qiongdongnan Basin, including the Yacheng Formation transitional facies mudstone, the Oligocene Lingshui Formation semi-enclosed marine facies mudstone, and the Miocene neritic-bathyal facies mudstone. The hydrocarbon generating conditions of the source

Potential on joint development of three-gas reservoirs in the Qiongdongnan Basin

The Innovation Geoscience
<p>Gas hydrates are typically found in the fine-grained sediments with low abundance and strong heterogeneity in the northern South China Sea. To date, although numerous gas hydrate reservoirs have been discovered, commercial exploitation remains highly challenging.

Tectonic Subsidence of Qiongdongnan Basin and Its Main Control Factors

Chinese Journal of Geophysics, 2008
AbstractBased on the data from 28 boreholes and the latest data of 3 seismic lines, the estimation of tectonic subsidence shows that the Qiongdongnan Basin (QDNB) experienced three episodes of rapid subsiding and one episode of slow subsiding in Cenozoic time.

Tectonics of the offshore Red River Fault recorded in the junction of the Yinggehai and Qiongdongnan Basins

Science China Earth Sciences, 2021
The Red River Fault, which originated from the southeastern margin of the Tibetan Plateau, has a great significance for obtaining a further understanding of the regional tectonics, topography and river catchment evolution, as well as the petroliferous sedimentary basin formation.

Geochemistry, origin and accumulation of natural gases in the deepwater area of the Qiongdongnan Basin, South China Sea [PDF]

Marine and Petroleum Geology, 2016
The Qiongdongnan Basin, South China Sea has received huge thickness (>12 km) of Tertiary-Quaternary sediments in the deepwater area to which great attention has been paid due to the recent discoveries of the SS22-1 and the SS17-2 commercial gas fields in

Geophysical properties of cap rocks in Qiongdongnan Basin, South China Sea

Marine and Petroleum Geology, 2000
Abstract Based on measured petrophysical properties and statistical methods, relationship between petrophysical properties and well log and seismic parameters are established empirically to evaluate the quality of cap rocks in Qiongdongnan Basin. Good cap rocks show high density and low sonic travel time.

Geochemical evidence of methane seepage in the sediments of the Qiongdongnan Basin, South China Sea

Chemical Geology, 2020
Abstract In this paper, the QS-1 sediments (3.64 m long; at 1500 m water depth) collected from the Qiongdongnan Basin were used to analyze the relationship between sedimentary geochemical anomalies and methane seepage. Mo-U covariation, Ce anomaly, and Mg/Ca-Sr/Ca end-member model were analyzed to identify the variations of redox environment and ...
