| 摘要: |
| 追溯一块古老地壳的形成演变历程,势必涉及地球的生成假说,这是一个诸多争论的问题。本文不拟过多地卷入地球的形成和初始地壳的争论,仅以在华北地块上稳定类型沉积的第一次出现和典型的盖层沉积的普遍发育为起始,研讨该地块盖层的沉积演变和我国北方大陆壳的形成历史。 |

| Abstract: |
| This paper deals with the formation and evolution of the North China continental crust and the controls of palaeotectonic movements on the sediments within the North China block on the basis of the study of the cycles in the sedimentary profiles and palaeogeography and ancient sediments within the block. Three stages for the formation of the continental cust have been distinguished, which exerted a tremendous influence on the biospheric evolution. |
