摘要

西沙海槽盆地位于南海北部陆坡上，是一个新生代深水盆地。盆地沉积物填充物厚度约为1500 ~ 8000m，由中心向南北逐渐变薄。沉积物在南北方向上呈带状分布。在地震剖面上，存在上部为沉降形成，下部为裂陷形成的双层构造。裂谷期形成的构造主要为“多米诺式半地堑”，即受一侧主要断裂(F1、F2、F3、F4、F5)控制的一系列半地堑。盆地演化经历了两个阶段:第一阶段为古新世-渐新世裂陷期，充填湖相沉积;第二阶段为中新世-第四纪沉降期，充填浅海或深海沉积。

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.
