| Abstract: | Based on the typical sections of latest regional geological surveying and analysing thelithologic assemblage,sedimentary type,and palaeontologic feature of the Lower Permian KaixinlingGroup and the Upper Permian Wuli Group,five litho-stratigraphic units and corresponding five bio-stratigraphic units have been set up in Permian System,representing the strata sequence and organismsuccession of Qixia-Changxing Period.The organism of this area can be merged into Tethys fauna andCathaysian flora.The Coal-fields,such as Wuli of Southern Qinghai,Shuanghu of Northern Xizangand Tuoba of Changdu all belong to a same Coal-bearing formation,and the Coal-forming age is fromMiddle Longtan period to Changxing period. |
