    The Discovery of Qingbaikouan Plutonite inT axorgan, Xinjiang,and Evidence from Zircon LA-ICP-MS U-Pb Dating of Intrusive Rock.

    • In the period of 1∶50000 field mapping, precambrian strata was distinguished from theLower Paleozoic strata,intruding the Neoproterozoic tonalite pluton. In situ zircon U-Pb LA-ICP-MS dating on the tonalite pluton zircons yielded an age of the 855±14 Ma and 836±12Ma,representing the tonalite pluton intruding age and being the only Neoproterozoic age in Karakorumbelt,which is important in studying of Karakorum Precambrian geological evolution.
