| 摘 要： | 塔里木盆地库车坳陷北部古近系主要发育扇三角洲——滨浅湖沉积体系。根据本地露头和岩心资料,将研究区古近系地层划分为5个三级层序。其中库姆格列木群沉积期发育3个三级层序,苏维依组沉积期发育2个三级层序。在此基础上建立了层序地层格架,并分析了研究区的古地理演化特征。

| Abstract: | north Kuche depression,Tarim Basion mainly developed fan deltas-shallow lake sedimentational system.Based on crops and well data of the studied area,this paper divides the Palaeogene into 5 third order sequences.The sedimentary stage of Ku mu ge lie mu group developed 3 third order sequences and the sedimentary stage of Su wei yi group developed 2 third order sequences.Based on this,this paper establishes the Sequence stratigraphic framework of the studied area,and analyses the palaeogeography evolution of ... |
