a) Alternation of beige marls (F6a), red clays (F6d), and finely laminated mudstone with teepee structures and desiccation cracks (F6b) (box) characteristic of intertidal depositional environment (FA6) (Imilchil Formation, sequence S4.2). b) Biostromes interbedded with bioclastic grainstone and beige marls, subtidal reef environment (FA7) (Imilchil Formation, transgressive systems tract of sequence S5). Biostromes are made of branchial and massive corals. The massive corals sometimes present « skullcaps » morphologies (box), typical of a depositional environment subject to an environmental stress. c) Subtidal environment with tidal channels and sandwaves (FA8) characterized by an alternation of marly deposits and oolitic/bioclastic channel bodies, one hundred to several hundred meters long (Imilchil Formation, transgressive systems tract of sequence S5). d) Several meters thick set of oblique crossbedding in oolitic grainstone deposits (F8a) typical of tidal sandwaves (Reyneck, 1963) (Imilchil Formation, transgressivesystems tract of sequence S5). e) Alternation of beige marls (F6a), fine- to medium-grained sandstone with wave ripples (F9a) (box) and bioclastic packstone/floatstone (F9b) characteristic of upper offshore environment (FA9) (Imilchil Formation, to the south of the Tassent ridge, sequence S4.2). f) Alternation of meter-thick to several-tens-of-meters thick intervals of red clays and tabular sandstone beds ten centimeters to one meter thick, interpreted as deposited in a distal alluvial environment (FA10) (Anemzi Formation in the mini-basin of Tilmi, sequence S5). g) Fine- to medium-grained sandstone, red to grey clays (Anemzi Formation).
