Abstract

Abstract

The paper describes the sedimentary environment, basin framework and tectonic paleogeography in different regions in the joint of Qinling, Qilian and eastern Kunlun, Northwest China. It analyzes the facies change, overlapping and time transverse of the strata from Early to Middle Triassic on the basis of rock assemblage and sediment characteristics and fossil assemblages. Then it discusses the rock assemblage and sediment characteristics and age of Naocangjiangou Formation and ended with the revision of its meaning. It is considered that Naocangjiangou Formation could have been formed in from Early to Middle Triassic, consisting of limestone and clastic rocks. The limestone occurs from its bottom to its top with changing facies in between. Furthermore, it expatiates the sedimentary and paleogeographical characters of western Qinling, Qilian and eastern Kunlun.
- Early-Middle Triassic,
- tectonic paleogeography,
- western Qinling,
