Abstract:
In order to understand the tectono-magma events in the southern margin of Altun in Early Neoproterozoic, the Yaganbuyang granitic gneiss in Mantelike area was selected for detailed studies of petrology, isotope chronology and petrochemistry. The results show that Yaganbuyang granitic gneiss is formed in Neoproterozoic Qingbaikou period, and the zircon U-Pb age is(880.3±3.4)Ma; the rock with obvious fractional distillation of LREE and HREE and the loss of HFSEs such as Nb,Ta,Zr and Hf, is magnesian granite in the peraluminous and calc-alkaline series, and has the characteristics of crustal remelting granite, which originates from the partial melting of base rock in the amphibolite facies of the lower crust and forms in the syn-collisional granite zone. It is suggested that the tectono-magma events in the southern margin of Altun has the possiblity of matching to the assemblage events of Rodinia supercontinent in Neoproterozoic, indicating that assemblage collision occurs between Tarim and Qaidam plates at the early time.
