In spite of the long-term research, sedimentary rocks of the Amery Group are still not properly examined which causes existence of various views on the geological framework and stratigraphy of sedimentary rocks today. This article contains basic concepts of the stratigraphy of sedimentary rocks of the Amery Group based on the new data discovered during the field seasons of the 48, 49, 50 and 51 Russian Antarctic Expeditions in 2002 - 2006. The conducted research allowed us to find out new information about the stratigraphy and the character of the relations between the stratons of the Amery Group. The criteria for determination of the local stratons are based on the structural and material features reflecting the peculiarities of the stratons formation. The total thickness of the investigated deposits of the Amery Group accounts for 2865 – 3015m
