摘要
南海北部陆缘盆地新生代发生过五次构造运动：晚白垩世－古新世的神狐运动、早－中始新世间的珠琼运动一幕、中－晚始新世间的珠琼运动二幕、晚渐新世的南海运动和中中新世末－晚中新世末的东沙运动。五次构造运动构成裂陷，裂后和块断升降三个演化阶段，与典型被动大陆边缘盆地在构造背景和热体制方面有明显差异。故珠江口盆地在含油气规律方面具有其独特性。
Five tectonic movements oecured in the continental margin basins in the northern part of the South China Sea :late Cretaceous-Paleocene Shenhu movement, the first episode of early-middle Eocene Zhu-Qiong movement, the second episode of middle—late Eocene Zhu-Qiong movement, late Oligocene South China Sea movement, and late middle Miocene-end of late Miocene Dongsha movement. Three evolution stages of faulting, post rifting and block faulting were resulted by these five movements, which gave obvious difference in regard to tectonic background and thermal histo- ry comparing with passive continental margin basins. Therefore, the PRM Basin has its unique oil and gas bearing laws.
