The Beiyixi Formation in Quruqtagh area is a volcanic-sedimentary succession which were related to breakup of Rodinia supercontinent. Our study don’t support the hypothesis based on the geochemical composition of the Neoproterozoic Beiyixi Formation sandstones. Chemical classification of the Beiyixi Formation sandstones indicates that the analyzed sediments are unstable wackes and litharenite.The sandstones are characterized by moderate SiO2contents(68.58% 72.97%)and low K2O/Na2O ratio(generally0.58 1.13)and moderate Fe2O T3+MgO contents(4.01% 7.50%).The REE patterns are characterized by LREE enrichment,flat HREE,andpoor negative Eu-and Ce-anomalies.CIA index(generally46 50)and Th/U ratio(4.10 6.15)suggest that these sediments were derived from source rocks with low-moderate weathering.And Zr/Sc and Th/Sc ratios illustrate that all sediments have undergone moderate degree of weathering and no significant sediment recycling,which indicates proximal provenances and poor sorting.Various diagrams for sedimentary provenance using major and trace elements show all the sediments studied were derived predominantly from felsic volcanic rocks source.Sediments were demonstrated to have come mainly from the north areas as indicated by restored paleo-current directions.Geochemical data for these rocks suggest a continental island arc setting.T ogether with regional geological evidence,the metasediments were deposited in an intra-arc basin.Key words Beiyixi Formation;Provenance analysis;Tectonic setting;Intra-arc basin;Quruqtagh;Xinjiang摘要库鲁克塔格位于南天山和塔里木盆地接合部,保留相对较完整的地层记录。
