English: (A) General aspect of the outcrop from Jebel Akenzoud (Dades Valley, Central High Atlas Basin, Morocco). The two rectangles indicate zoom in on selected portions of the outcrop. (B) Close-up view of the left-hand side of the panel. Lateral accretion within the ooidal shoal in the uppermost part of the infilling unit can be seen (white arrows). The black arrow points at the right edge of an inferred tidal channel within the uppermost infilling unit. (C) Stratigraphic correlation of sections TS1 and SB1 (this study) with Dades Valley composite13. From the bottom to the top, the green unit = lower host unit; orange unit = median infilling unit; blue unit = upper sealing unit, stratigraphically correlative to the T-OAE; yellow unit = rest of the sealing unit. Note that the 50 m incision affects the uppermost part of the Polymorphum Zone and is directly overlain by sedimentary rocks belonging to the T-OAE stratigraphic interval. (D) Close up view on the right-hand side shoulder of the infilling unit. The presence of a wedge-shaped sedimentary body (white arrow) hints at multiple sub-episodes of erosion and deposition during the infill of this unit. (E) Close up on the erosion surface affecting the lower host unit (SB1).
