Archaeocyath-Epiphyton reef-rimmed platform.
Platform marginal buildup facies are mainly composed of massive Archaeocyath-Epiphyton boundstone (AERPF4) and massive dendrolite (AERPF5).
Massive up-convex geometry (up to 70 m thick). Mesofabric characterized by erecting light-coloured aggregates/speckles intergrown with in-situ cup-shaped, branching and massive archaeocyaths or overturned fragments particularly in seaward portion. Bush-like calcified Epiphyton colonies dominate the bioconstructors with subordinate Renalcis elements and build up the skeletal/rigid framework. Inter-constructor cavities lined with submarine cements common. Constituting the core portions of phase S2 buildup complexes.
