A mudstone is a siliciclastic sedimentary rock that contains a mixture of silt- and clay-sized particles (at least 1/3 of each). 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.

Gaotai Formation, as a barrier to water, consisted of mudstone and lime mudstone with a lower permeability, so it was difficult for meteoric freshwater to get through this strata and dissolve the underlying strata.
