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.
期刊介绍：
Marine Geology and Quaternary Geology launched in 1981 is a bimonthly academic journal sponsored by Qingdao Institute of Marine Geology, China Geological Survey, and published by the Science Press, China.The journal aims to publish original, cutting-edge, and explorative scientific results in the field of marine geology and sea-land Quaternary geology. The journal focus on reporting the latest research achievements supported by National Natural Science Foundation Project, National Key Project and International Cooperation Project, with priority to the results in China seas, global ocean and three poles, and the comparative study results between offshore and land, regional and global scientific issues.
