摘    要:据磁性地层研究,并借助于同位素年龄测定和河谷地貌研究资料,库车河第三系可划分为(自老而新)库姆格列木群、苏雅依组、吉迪克组、康村组、库车组和西域组,第四系可划分为坎村组、乌苏群、新疆群和全新统,结合塔里木盆地及周缘的实际情况将第四系下限暂置于1.6MaB.P.,上、下第三系的分界时限为24.0MaB.P

关 键 词:新生界,第三系,第四系,磁性地层,库车河,新疆

Abstract:Based on the study of magnetostratigraphy and combined with isotopic dating,as well as the data on valley topography,the Tertiary of Kuche River area may be upwardly subdivided into the Kumugeliemu Group (E 1-2 k), Suweiyi Formation (E 3s), Jidike Formation(N 1 1 j),Kangcun Formation (N 2 1k),Kuche Formation (N 1 2k) and Xiyu Formation (N 2 2x) ,and the Quaternary System into Kancun Formation (Q 1k),Wusu Group (Q 2w),Xinjiang Group (Q 3x) and Holocene Series (Q 4) respectively,taking the practical conditions of both the Tarim Basin and the surrounding regions into account we can infer that the lower limit of Quaternary System may formed at about 1.6 Ma B.P.,limit between Paleogene and Neogene about is 24.0 Ma B.P.
Keywords:Cenozoic  Quaternary  Tertiary   magnetostratigraphy  Kuche River  Xinjiang
