Abstract

[The Upper Proterozoic of the Tarim craton can be divided into the upper and lower parts. The lower part belongs to the Qingbaikouan System (1.0–0.85 Ga), including epimetamorphic carbonate–clastic rock series in the northeastern and southwestern margins of the craton, and blueschists in the northwestern margin of the craton. The upper part is the Nanhuan System and the Sinian System (0.85–0.54 Ga), which occur in Aksu area of northwest Tarim, Quruqtagh area of northeast Tarim, and Yecheng area of southwest Tarim, preserving rich and varied geological records, characterized by the development of rift sedimentary formation, multiphase tillites, and magmatic activities. Four glacial periods have been recognized in Quruqtagh area, including Bayixi glaciation of 740–732 Ma, Altungal and Tereeken glaciations of 725–615 Ma, and Hankalchough glaciation of 615–542 Ma, and their international correlation has been discussed. Tarim Movement results in a stable cratonic crustal structure in the Tarim craton and is also an intense response of the Tarim craton to Rodinia supercontinent event. The Late Proterozoic magmatic activities in the Tarim craton are characterized by wide distribution and multiple episodes, and are divided into four developing phases including 820–800, 780–760, 740–730, and 650–630 Ma.]
