中国的叠合盆地和改造盆地的演化有着复杂的构造体制转换和频繁的旋回性.南方中、古生界海相盆地的演化是多旋回构造运动的典型代表,其发展和现今状态具有复杂的盆地叠加和构造改造等多旋回演化的属性.基于构造动力学差异和时空组合变化对南方海相油气成藏特征、聚集规律及成藏旋回性的直接影响和核心控制作用,认为南方多旋回叠合盆地或改造盆地的油气成藏演化具有"构造 -成藏旋回"的特性.通过对构造旋回和成藏旋回的对比分析,将南方中、古生界海相盆地油气成藏划分为四大构造-成藏旋回,即加里东期构造 -成藏旋回、晚印支-早燕山期构造-成藏旋回、晚燕山-早喜马拉雅期构造-成藏旋回和晚喜马拉雅期构造-成藏旋回.研究进一步揭示了每一个构造 -成藏旋回所具有的独特的、受控于该旋回构造作用的油气聚集模式和分布规律.

China's superimposed basins and relic basins feature in complex transformation of tectonic frameworks and multiple cyclicity.The evolution history of marine basins in Southern China represents a typical polycyclic movement.Their development and present status are characterized by basin superimposition and tectonic reworking.Based on the direct influences and key control of the tectonic dynamic differences and their temporal and spatial variations on hydrocarbon accumulation and its cyclicity in the marine strata in Southern China,the authors suggest that the hydrocarbon pooling in the polycyclic superimposed or relic basins in Southern China feature in "tectonic-pooling cyclicity".Based on correlation of tectonic cycles and hydrocarbon pooling cycles,hydrocarbon pooling in the Mesozoic-Palaeozoic marine strata can be divided into four tectonic-pooling cycles,namely the Caledonian,the late Indosinian-early Yanshan,the late Yanshan-early Himalayan and the late Himalayan cycles.Further study reveals that each tectonic-poolying cycle has its unique hydrocarbon accumulation and distribution controlled by its tectonic cycle.
