| 摘 要： | 北部湾拗陷位于海南岛西面,目前为一半封闭浅海区,拗陷在前白垩系基底上发育起来,接受中、新生代沉积约3—4千米。笔者在拗陷的钻井岩芯中发现浊积岩。该凹陷长轴北东东向,南北缘有同生断层发育,钻井位于北部同生断层南面的断层上盘。岩芯表明,上第三系为浅海相沉积,下第三系缺少标准化石,按岩性分三个岩组:下部红色岩组,中部暗色岩组和上部杂色岩组。浊积岩系位于暗色岩组的下段(图1)。

| Abstract: | The Beibu Gulf is a depressed sedimentary region formed in Meso-Cenozoic time.In 1977-1978 the Paleogene turbidites were found in the drilling cores from this region.Based upon the internal texture,structure,composition and other characteristics of this horizon this paper deals with the features of the turbidites and shows that the materials constituting this series originated from the land blocks around this depression.These turbidites controlled by contemporaneous fault seem to be the continental margin type and show a pulsative feature. |
