Sill swarms and hydrothermal vents in the Qiongdongnan Basin, northern South China Sea
Geosystems and Geoenvironment, 2022 Sills and hydrothermal vents are commonly observed in sedimentary basins. However, not all sills could generate overlying hydrothermal vents, and whether a sill generates a hydrothermal vent or not is still poorly constrained.

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).
