Composite log of the butte Iouton succession compiling the depositional textures, the lithofacies stacking pattern, the interpreted transgressive-regressive (T-R) cycles, carbonate grain composition of limestones after point-counting on thin-sections, the relative abundance of selected preserved biota, δ¹⁸O and δ¹³C vertical changes and estimated salinity domains. See Figure2 for detailed legend.
