Abstract: The mantle pluming once caused the formation of an aulacogen called the Kuruktag-Manjiar aulacogen in northeastern Tarim plate during the Late Neoproterozoic to Early Palaeozoic. In the Kuruktag-Manjiar zone, the intermediate-acidic and basic bimodal volcanic formations, deep-water carbonate rocks and flysch depositional systems which are typical of rift basin deposits were developed during the the Early Sinian to the Ordovician. Later on the Upper Carboniferous-Permian strata are missing. Till the Mesozoic, the continental depositional systems began to be developed. All these reflect intense orogenic processes, and the uplifting and collapse of the basin cited above. The stratigraphic sequences in the basin are characteristic of typical aulacogen depositional systems, and recorded complete history of tectonic evolution from the initiation to termination of the Kuruktag-Manjiar aulacogen.
