Lime mudstone.
Massive lime mudstone without bioturbation, subaerial exposures and sedimentary structures generated by wave or current, as well as the absence of organisms, combined with thin-bedded lime mudstone of intra-mounds indicate that deposition took place in a low-energy environment, likely below the photic zone.
