Conglomerates (F10 facies) and sandstones (F11 facies). (A) Core photograph showing a polymictic clast supported conglomerate. The white arrows indicate pendant cements and/or micrite coating around the clasts. (B) Core photograph of a siliciclastic-rich sandstone (F11 facies). The lithic fragment indicated by the white arrow consists of a tufa clast (further details in Fig. 8). (C) Thin section showing the poor sorting of the clasts and the sandy matrix within the conglomerates F10 (Carb = carbonate lithoclasts). Notice the thin micritic coating around the grains. (D) Thin section photograph exhibiting the arrangement of sheet minerals (e.g., mica) in F11 sandstones as outlined by the arrows and that may suggest current ripples (PPL).
