Abstract: On the basis of analyses on the detrital composition and structural feature of sandstone, heavy mineral combination, ZTR maturity index, seismic profiles and sedimentary characteristics, it is considered that there were three external provenances in the hinterland of Junggar basin when the Qingshuihe formation of Early Cretaceous deposited: the north provenance, the west?northwest provenance and the east provenance. Also, the intrabasinal provenance existed in the early period of Qingshuihe formation, which came from the deposits of Toutunhe formation, Xishanyao formation and Sangonghe formation of the Cretaceous in Chepaizi?Mosuowan palaeohigh
