中国沉积盆地演化与联合古陆的形成和裂解

中国沉积盆地演化与全球动力学体系有关,可以划分为裂陷盆地序列、压陷盆地序列和走滑盆地序列。在空间上受东特提斯构造体系域与西太平洋构造体系域的制约,在时间上受联合古陆形成和裂解两个构造阶段的影响。因此,在各类原型盆地基础上可以产生反转盆地和复合盆地。中、新生代盆地与古生代盆地之间存在着新生性、再生性和反转性等关系。

EVOLUTION OF SEDIMENTARY BASINS IN CHINA AND ITS RELATIONSHIP WITH FORMATION AND BREAK-UP OF PANGEA

The sedimentary basins in China fall into three tectonic categories: extentional, con- tractional and shearing. They were spatially subjected to eastern Tethyan tectonism and western Pacific tectonism and temporally influenced by the formation and break-up of Pangea. Thus it was possible for inversion basins or composite basins to occur in archetype basins. The relationship hetween Mesozoic or Cenozoic basins and Palaeozoic basins may be reformed, reactivated or replaced.
