Abstract: Based on the theory and technology of Cross′s highresolution sequence stratigraphy, and two longterm, five middleterm and above ten shortterm cyclic sequences from Xiagou Formation of Lower Cretaceous in Qingxi Sag, Jiuquan Basin were classified. The structure types, stacking patterns, distributing mode and development relation to reservoir sand body of shortterm, middleterm, longterm cyclic sequences are analyzed. The sourcereservoirseal associations and the plane distribution rule of ferrodolomitealbite exhalative rock in the chronostratigraghic framework are discussed in detail.
