| 摘 要： | 通过对太平洋和古亚洲洋演化特征的讨论，可以为辽河（岩）群演化历史研究提供许多宝贵的启示.辽河（岩）群不可能是夭亡的裂谷，至少达到了大西洋阶段和太平洋阶段的洋盆.洋盆的闭合挤压造山作用，是一个漫长的（可能需要数亿年）递进变形过程，在此期间形成的所有构造形迹可归纳为一期构造.辽河（岩）群中的面理，以构造置换面理为主，因此，该套地层不适合按照史密斯地层学原理开展地层学研究，应采用岩性填图方法恢复其本来面貌.

| Abstract: | Research on the evolution characteristics of the Pacific Ocean and Paleo-Asian Ocean gives us some enlightenment for the forming history of Liaohe Group. It can be inferred that the Liaohe Group is not a vanished rift but more likely reaches the oceanic basin of at least Atlantic and Pacific stages. The closing compressive orogeny of ocean basin is a long progressive deformation process which may last several hundred million years. All the structural features formed in the process belong to the same stage. The foliation in Liaohe Group is mainly structural replaced foliation. Therefore the strata should be restored as what it really is by lithologic mapping rather than the Smith stratigraphy principle. |
