Fig. 13. (A) Detailed sedimentary logs (depths in m) showing sedimentology, architectural element and key surfaces in the
northern area (localities N1 to 4). (B) A schematic presentation of a possible depositional scenario for the AU8. Note the rela-
tively similar palaeocurrent directions. (C) Photo of upward facies transition across the flooding surface FSf that separates the
sandy heterolithic TDEC and muddy heterolithic WDDL elements at locality N4 (measured section 29). (D) Photo of matrix-
supported conglomerate bed directly overlying the combined SU2/TS5 unconformity surface at locality N3 (measured sec-
