Lower Grey and White Limestones (≈11 m) (Plate 1, c):
This interval is composed of dm-to m-thick layers of Grey and white, micritic and calcarenitic limestones with blocky fractures. Thalassinoides burrows are rare. Occasionally, the top is composed of stromatolitic limestones. The interval is capped by a regional hardground, which [is] bored and biogenically encrusted by oysters.
