The embedded rudists form decimeter-scale biostromes. Lithofacies association 6 (L6): floatstone with stromatoporoids (Figs. 6f, 7i, j). This association is organized into bodies of metre-scale and lenticular morphology. The presence of any primary carbonate mud precludes a classification of grainstone. A study of the use of carbonate classification systems by Lokier and Al Junaibi (2016) highlighted that the most common source of confusion in the classification of grainstone was to misidentify fine-grained internal micrite, generated by in-situ processes, as clay–silt grade sediment - thus resulting in the misidentification of grainstone as packstone.
