通过对札达盆地河湖相地层的野外地质调查和剖面实测,对分布于盆地内的新近系上新统—第四系下更新统地层进行了详细的研究和划分,重新厘定了该区上新世—早更新世岩石地层单元,建立了生物地层和年代地层层序。首次提出了该区上新统—下更新统三分方案,将该套河湖相地层重新划分为第四系下更新统香孜组(Qp1-1x)、新近系上新统古格组(N22g)和上新统托林组(N21t)3个组、7个沉积相、11个岩性段,并为确定上新统与下更新统的界线位置提出了具体意见,为青藏高原乃至全球新近系上新统与第四系的研究、划分提供了重要依据。
Based on the field geological survey and profile survey of the rivers and lakes facies in the Zanda Basin, the Neo-Pleistocene-Quaternary Pleistocene strata distributed in the basin were studied and classified in detail. Pliocene-Early Pleistocene lithostratigraphic units, the establishment of biological strata and chronostratigraphic sequence. For the first time, the third scheme of the Upper Paleocene-Lower Pleistocene was proposed and the system was reclassified into Qp1-1x, Qp1-1x, Neogene Furuiji Formation N22g) and the Upper Pleistocene Toxen Group (N21t), three sedimentary facies and eleven lithologic sections, and put forward specific suggestions for determining the location of the boundary between the Pliocene and the Lower Pleistocene. The Neogene and Quaternary systems of the Neogene have provided an important basis for the study.
