| 摘 要： | 根据岩石地层划分、对比理论和原则，对青藏高原主体范围内的前寒武纪地层进行了岩石地层和地质年代的划分，建立了岩石组合特征的标志及其上、下序列关系，提出了划分、对比意见。最后讨论了本区元古宙重大地质事件和基底性质，得出了本区无古宙地层纵向四分、横向二分的结论。

| Abstract: | Precambrian petrostratigraphic division and correlation in the Qinghai-Xizang Plateau region are made on the basis of theory and principle of petrostratigraphic division and correlation. Indication of rock association and sequence relation are proposed for the division and correlation. Make an approach to major geologic events in the Proterozoic and the basement features,reaching a conclusion of longitudinal division into four and lateral division into two of the Proterozoic Erathem. |
