The paleoflow direction of the basal conglomerate of the Changzhougou formation is obtained by the paleocurrent analysis of certain sedimentary structures,and the ancient sedimentary environment of the Qian’an Region is determined by observing the psephicity and gradation of gravel in conglomerate.The results show that the paleoflow direction is from northwest to southwest,and the paleocurrent data manifest a single-peak style in a rose diagram.The average paleoflow direction in the Qian’an region is 265°.The basal conglomerate is of littoral facies,and the sediments of conglomerates are mainly sourced from Shanhaiguan. 展开更多
