Fig. 12. (A) Photo of locality S5 (measured section 13) show the thick sandstone-dominated TDSS and FTT architectural ele-
ments indicating high rate of sediment input and rate of creation of accommodation space. The AU4 is interpreted as a major
distributary system (10 to 15 m thick and tens of metres-wide) at this locality. The overlying sandy heterolithic deltaic TDDC
and muddy heterolithic TDDF elements define the local deltaic system within an overall retrogradational AU5. Note that the
allostratigraphic unit AU6 is absent in this locality. (B) Detailed sedimentary logs show sedimentology, architectural elements
and key surfaces at locality S5 (measured sections 12 to 14). (C) Photo of a 12 m thick upward-coarsening deltaic architectural
