根据札达盆地河湖相地层实测剖面中的接触关系、沉积旋回、沉积体系、岩相、岩性、古生物特征和ESR、古地磁测年结果,笔者对札达盆地上新统—早更新统河湖相地层进行了重新划分和时代确定。结合该套河湖相沉积的岩石地层、生物地层、年代地层、磁性地层、层序地层和地质构造事件,对札达盆地上新统—早更新统河湖相地层进行了多重地层的划分与对比。将札达盆地河湖相地层划分为3个组、4个沉积相、7个沉积亚相、11个岩性段。由新到老划分为:早更新统香孜组(Qp1-1x)、上新统古格组(N22g)和上新统托林组(N21t)。
According to the contact relationships, sedimentary cycles, sedimentary systems, lithofacies, lithology, paleontology, ESR and paleomagnetic dating in the measured sections of the rivers and lakes of the Zanda Basin, River and lake strata have been re-divided and the times to determine. Based on the lithostratigraphic, biostratigraphic, age stratigraphic, magnetic stratigraphy, sequence stratigraphy and geological tectonic events of the lacustrine facies sediments, the stratigraphic division of the Upper Pleistocene-Early Pleistocene lacustrine facies in the Zanda Basin is divided into Compared. The lacustrine facies and strata in the Zanda Basin are divided into three groups, four sedimentary facies, seven sedimentary subfacies and eleven lithologic sections. It is divided into new and old by the Early Pleistocene Qixi Formation (Qp1-1x), the Upper Pleistocene Guogu Formation (N22g) and the Upper Pleistocene Tolin Group (N21t).
