Lithology and environment
Primary lithology:medium,shelly/skeletal lithified sandy,calcareous mudstone
Secondary lithology:"cross stratification",shelly/skeletal lithified wackestone
Lithology description: Bioclastic sandy mudstones (sand mainly composed of fenestrate bryozoa and brachiopod debris with a broad peak in the medium to coarse size fractions). Terrigenous mud matrix. Decreasing siliciclastic sand (mainly very fine) content upsection. High density of subaligned fenestrate bryozoan sheets. Lithology 2: Indurated wackestones. Very low angle trough cross-bedding, skeletal lags. Large bioclasts in random orientations or in small aligned clusters.
Environment:transition zone/lower shoreface
Geology comments: Normal marine, well oxygenated conditions within storm wave base. Local storm winnowing and bryozoan meadows.
