Abstract：The recognization of fan delta and braided-river delta of the Upper Karamay Formation in Hongshanzui area in Junggar Basin has always been concerning the geologists in the field of hydrocarbon sedimentology. Depositional analysis based on lithofacies supplemented by the macroscopic distribution mode of sandbody is helpful for distinguishing the two kinds of deltas. Cross-bedded conglomerate lithofacies(Gi,Gt,Gp)and massive gravel lithofacies(Gmm,Gcm,Gcs)were developed in fan delta,with sandy lithofacies(St,Sp,Sm and Sh, etc.)developed in braided-river delta in Hongshanzui area. Debris flows and density flows were indicated by six lithofacies associations in fan delta system,with unobvious rhythm feature. Seven lithofacies associations in braided-river delta show that the traction currents and positive rhythm feature are more significant. Steep slope and abundant sediments contributed to a thick stacked sandbody with limited distribution in the fan delta system. Gentle slope,insufficient sediments supply caused a thin sandbody with board distribution in the braided-river delta,mainly showing isolated contacts between the sandbodies.
