The terminology of "mudstone" is not to be confused with the Dunham classification scheme for limestones. In Dunham's classification, a mudstone is any limestone containing less than ten percent carbonate grains.The 12 lithologies recognized within the stratigraphic sections reflect the interaction between contemporaneous shallow-water carbonate ramp environments and a siliciclastic-dominated intrashelf basin. Deposition on the carbonate ramp was in the form of lime mudstone and wackestone and oolitic and oncolitic packstone and grainstone.

Note that a lime mudstone is a carbonate rock. A rock composed of siliciclastic mud but with carbonate cement should be treated as one of the fine-grained siliciclastic rocks ("shale", claystone, mudstone, siltstone). wackestone: a limestone composed of lime mud (micrite) and greater than 10% grains (ooids, peloids, bioclasts, or intraclasts ...
