摘要

The Tarim Block is one of the main three continental blocks （plates） in China. It has typical double layers structure consisting of the Precambrian basement and Neoproterozoic to Cambrian cover. In this contribution, the authors integrated the recently published Precambrian studies of the Tarim block and have a detailed analyzing on these data. The authors constructed its Precambrian evolution stages, courses and its tectonomagmatic-metamorphic concurrence to the global-scale suppercontinent evolution. Importantly, the authors discussed the sedimentary and metamorphic ages of the blueschist-bearing Aksu Group according to recently obtained geochronological data and the regional geology, in combination with the previous studies on the Neoproterozoic igneous rocks, the authors argued that the Tarim Block could assemblage to the northern side of the Australia during Late Mesoproterozoic to Early Neoproterozoic （1 000~900 Ma）.
