Interactions between Down-Slope and Along-Slope Processes on the Northern Slope of South China Sea:Products,Processes,and Depositional Model
摘要
Abstract
Using integrations of seismic data and core data,interactions between down-slope and along-slope processes had been studied.Gravity flow deposits and contourites are well developed in northern South China Sea,including canyon,unidirectionally migrational channels,levees,lobes,drifts and so on. Unidirectionally migrating channels result from interactions between gravity flow and contour current with migrating directions are northeast (NE)and west-southwest (WSW),respectively.Drifts consisted of clay and muddy silt could be divided into giant elongated,confined and slope sheeted drifts.NE-migrating channels and drifts are widespread at water depths of 200 m to 1 200 m.By contrast,lobes,drifts and few WSW-migrating are developed at depths of 1 200 m to 3 000 m.Contourites distribute on the both sides of canyon,channel and lobe,which result from reworking the fine-grained deposits of gravity flow.关键词
