摘 要：The Tiekelik Belt includes a large outcrop area of Precambrian continental crust,which is exposed along the southwestern margin of the Tarim Craton,NW *** is characterized by the occurrence of high-grade metamorphic rocks and volcano-sedimentary *** this contribution,we present zircon U-Pb results from ten samples of rocks from these volcano-sedimentary successions for provenance and age determinations,and geochemical analyses on basalts of the bimodal volcanic rocks from the Sailajiazitage *** schist and paragneiss samples from the Ailiankate Group contain numerous zircons with ages of 650–850 Ma,suggesting that this group was deposited after the late Neoproterozoic and is not part of the Paleoproterozoic
