In this paper the attributes of the rheomorphic structures are for the first time dealt with in details and the general features of synsedimentary deforma- tion structures both at home and abroad are summarized systematically.Thro- ugh comparison,nine.applicable criteria for distinguishing rheomorphic stru- ctures from synsedimentary deformation structures are proposed.
