“…Those bipartite beds would be described as sgbceSM in the present scheme, but a separated new subfacies (sglSM, plane-stratified to graded to laminated sand-mud couplets) might also be distinguished for descriptive and classification purposes. The same is true of other, relatively uncommon bed types, such as gsmGS (Aalto, 1989), sgGyS (Slaczka & Thompson, 1981), gxlSM (Hubert, 1966a, b;Thompson & Thomasson, 1969;Spalletti et al, 1989), xlSM (Thompson & Thomasson, 1969;Rocheleau & Lajoie, 1974;Mutti, 1979;Mutti & Normark, 1987), glMT Anastasakis &Piper, 1991) and mM (McCave &Jones, 1988;Jones & McCave, 1990). Moreover, some additional descriptive code-keys may be introduced to denote specific sedimentary structures and to distinguish new, less typical subfacies, if necessary (e.g.…”
