Abstract: Anastomosed river deposits of Fuxin Formation in Tiefa basin, one of the Late Mesozoic semigraben basin, are developed in the progradational system accompanied by the process of the lake reg ression betw een alluvial fa ns inside the fault of the basin edge and lake deltas. A great quantity of geological data of drillings and pits reveal the characteristics of facies of the channel, the stream bank and the wet land in the anastomosed river deposits and debris flow deposit is a particular genetic type among channel facies. The prosperous development of the sedimentary system of the anastomosed river is the main part in the genetic stratigraphic units, and the genetic stratig raphic units are ended by the decline of the sedimentary system of the anastomosed river accompanied by a great area of peaty swamp. Important conditions of the developing of the anastomosed river are frequent activity of the fault in the basin edge, large rate of the subsidence and deposit filling in the basin and small slope of channels.
