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
According to the study of magnetic stratigraphy and by means of isotopic dating and study of valley and landforms, the Kuqahe Tertiary can be divided into (from old to new) Kummel Lieutenant, Suyayei Formation, Jidike Formation, Kang Village Group, Kuche Group and Western Group, the Quaternary can be divided into the Kemura Formation, Wusu Group, Xinjiang Group and Holocene, combined with the actual situation in the Tarim Basin and the Quaternary lower limit temporarily placed at 1.6MaB. P. , The upper and lower Tertiary demarcation time limit of 24.0MaB. P
