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).
