Analysis of the Tectono一sedimentary Setting of the Bolhinur Mt.Formation ( Upper Silurian ) in the Bolhinur Mt.Region，Xinjiang

Li Yongtie

Abstract

The Bolhinur Mt.Formation of the Upper Silurian is widely distributed in the Bolhinur Mt.region.The Formation was formed in the closing stage of the Bolhinur Early Palaeozoic Aulacogen and is famous for its purplish red sediments.Having analysed sedimentologic，petrologic and petrochemical features, the author probes into the tectonic setting of the Bolhinur Mt.Formation of the Upper Silurian and concludes that the Fomation was turbidity current sediments and formed in close relationship with an active continental margin.The source area of the Fomation was mainly southern"Yining oldland",which had certain continental crust and middle maturity.
