THE STRUCTURAL FEATURES OF XISHA TROUGH BASIN: THE STRUCTURAL FEATURES OF XISHA TROUGH BASIN
The Xisha Trough Basin,located on the continental slope of the northern South China Sea,is a Cenozoic deepwater basin.The sediment fill in the basin is about 1500 ~ 8000m in thickness,and becomes thinner from the center towards north and south.The sediments show a zonal distribution pattern in north-south direction.In seismic profiles,there is double-layer structure,of which the upper is formed with subsidence and the lower with rifting.The structures formed in the rifting stage were mainly of "Domino-style of half-graben",a series of half-graben controlled by major faults on one side(F1,F2,F3,F4,F5).The basin has experienced two stages of evolution: the first stage underwent rifting through Paleocene-Oligocene and filled with lacustrine deposits,the second stage underwent subsidence through Miocene-Quaternary and filled shallow or bathyal sediments.
