Deep-water sediment cycles in the Qiongdongnan Basin [PDF]

Chinese Science Bulletin, 2015
Three sediment cycles were identified by 3-D seismic data within early Pleistocene to present strata on the northwestern slope (15°3000-16°3000E) of the Qiongdongnan Basin. The sediment cycles are characterized by basal mass transport deposits (MTDs) overlain by channel-levee deposits (CLDs).

A Flat‐Lying Transitional Free Gas to Gas Hydrate System in a Sand Layer in the Qiongdongnan Basin of the South China Sea

Geophysical Research Letters, Volume 50, Issue 24, 28 December 2023., 2023
Abstract Most marine gas hydrate systems follow a vertical pattern with hydrate overlying free gas. Here we document the discovery of a gas to hydrate system in a horizontal sand layer in the Qiongdongnan Basin of the South China Sea. Eight wells were drilled by the Guangzhou Marine Geological Survey in 2021–2022 to investigate the occurrence and ...

An Epifaunal Community Succession Sequence Driven by the Biogeochemical Footprint With Different Methane Seepage Intensity of the Deep Seafloor

Earth's Future, Volume 11, Issue 11, November 2023., 2023
Abstract Methane seepage, generated from natural processes or gas hydrate dissociation, drives the development of cold seep ecosystems and leads to atmosphere methane emission, thereby influencing climate change. Uncovering the intrinsic interactions among methane seepage intensities, biogeochemical processes in the sediment, and benthic community ...
