Abstract: This study shows that it was a littoral- and neritic- facies during sedimentation of the Lower Carboniferous Heishantou Formation and Nanmingshui Formation. Several sets of "basal conglomerates" developped between the two Formation and the first sub-formation of Nanmingshui. The conglomerates, usually as a shape of lens and not far-extending, are occurrences of subaqueous channel when rivers flow into the sea, but not basal conglomerates previously considered.Lateral comparison of conglomerate characteristics and the study of oblique beddings and asymmetrical ripple mark indicate that the provenance is in the direction of NE, and the paleocurrence direction concentrates in 93°-125°.The contact relationship between Heishantou Fm. and Nanmingshui Fm. is conformable and successive. It is not an unconformity of plate collision between Junggar block and Siberia plate.
