The Middle Devonian to Lower Mississippian siliciclastic strata, deposited by the Catskill Delta, includes black shale, gray shale, sandstone, red beds, and minor argillaceous limestone.

For example, " argillaceous limestones " are limestones consisting predominantly of calcium carbonate, but including 10-40 % of clay minerals : such limestones, when soft, are often called marls.

They also make " Ciment Prompt "-a fast-setting natural cement, at La Perelle, by burning at moderate temperature an unground argillaceous limestone obtained from an underground mine in the Chartreuse Mountains.

Low-level and intermediate-level radioactive waste produced by the three Ontario nuclear power plants in operation are managed by the Western Waste Management Facility ( WWMF ) located at the Bruce nuclear site in Deep Geologic Repository would be dug 680 metres below the surface in and argillaceous limestone layer isolated beneath 200 metres of shale.

It divided the sedimentary basin now into two major facies domains : a deeper western domain open to the Atlantic and undergoing infratidal sedimentation ( black to blueish argillaceous limestones rich in benthic organisms, microfilaments, and ammonites ) and a shallow, enclosed, eastern domain with intertidal sedimentation ( variable carbonate facies like pseudo-oolites and banded dolomites, but also anhydrite-bearing evaporites ).
