摘要
南海北部西区新生界天然热释光强度为0.22×102~17×102(平均2×102),并且随着地层时代变新而呈递增趋势。南海北部西区特别是新生代以来,至少发生过如下几次重要的构造热事件:前新生代(可能是多次)、老第三纪末─新第三纪初和新第三纪晚期,从而造就了研究区独特的新生代沉积建造和构造热场格局及相关的油气藏类型。南海北部西区油气田的形成与定位,主要是老第三纪末─新第三纪初构造热事件作用的结果。
The natural thermoluminescence of Cenozoic ranges from 0.22×102 to 17×102 with an average 2×102 in northwestern South China Sea,increasing upward with the strata.At least the following important regional tectonothermal events have happened in northwestern South China Sea since Cenozoic,i.e.those happened at the beginning of Cenozoic,the end of Paleogene or the begining of Neogene and the end of Neogene,resulting in the unique Cenozoic sedimentary formation,tectonic framework and related oil/gas pools there.The accumulation of the oil/gas pools have been mainly affected by the tectonothermal event in northwestern South China Sea at the end of Paleogene or the beginning of Neogene.
