| 摘 要： | 南沙海域主要的新生代盆地及其类型为:(1)曾母盆地,走滑一周缘前陆型;(2)万安盆地,拉张剪切型;(3)沙巴一文莱盆地,弧前盆地;(4)湄公河盆地,陆内断陷型;(5)西纳土纳盆地,剪切拉张型。这些盆地沉积厚度大多在3000m 以上,最厚大干12000m,含海、陆相沉积,具较好的油气勘探前景。其演化历史最早的始于始新世,最晚的始于渐新世晚期,文中对各盆地演化历史作了对比。

| Abstract: | The main basins and types are as follows:(1) Zengmu Basin,strike-slip-peripheral foreland basin,(2) Wan'an Basin,pull-apart-shear basin,(3) Shaba-Wenlai Basin, forearc basin,(4) Meigonghe Basin.intracontinental fault basin;and (5) Xi'natuna Basin,shear-pull-apart basin. The sedimentary depths are mostly more than 3000m,and thicker ones surpass 12000m.The basins are prospective for oil and gas exploration,involving both the marine and conti- nental deposits.The evolution of the basins began earliest in Eocene,and latest in late Oligocene.The correlation of evo- lution history of the basins is given in table 2. |
