| 摘 要： | 依据造山带的大地构造环境、物质基础及形成时代、变质程度 ,并通过与祁连、北秦岭地层的对比 ,将祁连—北秦岭接合部位晚古生代前的地层划分为古元古界秦岭群、中元古界陇山群、震旦系—奥陶系的李子园群、葫芦河群、陈家河群 ,并建议将它们列入甘肃地层之中。

| Abstract: | In accordance with tectonic setting,material base and forming age,degree of metamorphism in orogenic belt,and getting through correlation of Qilian and north Qinling strata,the pre-late Paleozoic stratum at the junction position of Qilian and north Qinling is devided into Paleoproterozoic Erathem Qinling group,Mesoproterozoic Longshan group,Sinian-Qrdovician System Liziyuan group,Huluhe group and Chenjiahe group.We suggest that all of them be listed into Gansu strata. |
