There are many Precambrian blocks outcrop at the Tiekelike, Altyn Tagh, Qilian Shan, Qaidam and its surroundings along the northern margin of the Tibetan Plateau. All these old blocks were distributed in the Qiling-Qilian-Kunlun orogenic belt and reworked by Palaeozoic orogenesis. Recent studies on the chronostratigraphic frameworks, lithological associations and tectonic affinities of these Precambrian blocks indicate that: 1）There are identical 2.5～2.2 Ga and 2.1～1.7 Ga tectonothermal and post ～1.7 Ga sedimentary events in the Tiekelik, North Altyn-Dunhuang, Alashan blocks, and Quanji massif, which are likely related to the dispersal of Neoarchaean‘Kenorland’and the formation of the Columbia supercontinent. 2）Many chronostratigraphic frameworks were revised and the new Precambrian lithostratigraphic division of the Tiekelike belt was proposed. 3）A Neoproterozoic volcano-sedimentary rift basin was suggested to have developed along the southwestern margin of the Tarim Craton. The occurence of ca. 1 000～830 Ma rift-related volcanic rocks unraveles Neoproterozoic regional extensional processes in the southern margin of the Tarim-North China Craton, which allow us to speculate on the correlation of the Tarim and North China Cratons during the Neoproterozoic. 4）The similarities of magmatism and metamorphism ages in the Altyn Tagh-North Qaidam-Qilian-East Kunlun suggest that extensive early Neoproterozoic tectonic complexes had developed along the northern margin of the Tibetan Plateau. These complexes may represent exotic fragments accreted to the Tarim Craton during the Palaeozoic.
