The southern Appalachian part of the Cambrian–Ordovician passive margin succession of the great American carbonate bank extends from the Lower Cambrian to the lower Middle Ordovician, is as much as km ( mi) thick, and has long-term subsidence rates exceeding 5 cm (2 in.)/k.y.

Subsiding depocenters separated by arches controlled sediment thickness. Subjacent Cambrian carbonates, the Lower to Middle Ordovician Beekmantown Group, and the Middle Ordovician Loysburg Formation were deposited on a rimmed carbonate shelf, with restricted circulation and wave action, on which vast peritidal and shallow water carbonate facies flourished (Goldhammer and others, ; Faill, ).

Regional facies for the Upper Ordovician Series (global classification) of eastern North America consist of clean (pure) carbonates, mixed carbonates and terrigenous clastics, shale, terrigenous clastics coarser than shale, and terrigenous clastics prograding over carbonates.

The last facies is characteristic of the Upper Ordovician. The Cambro-Ordovician carbonates discussed in this paper include all the limestones and dolomites from Late Cambrian age up through the lower Middle Ordovician (Chazy).

The Ordovician was a time of calcite sea geochemistry in which low-magnesium calcite was the primary inorganic marine precipitate of calcium carbonate. Carbonate hardgrounds were thus very common, along with calcitic ooids, calcitic cements, and invertebrate faunas.

The MRB represents a stiff panel of Middle Ordovician (Llanvirn) through mid-Devonian (late Emsian–early Eifelian) shelf carbonates, graptolitic shales and flysch that ranges from to m in thickness. The beam is bound by the two ductile layers and includes three to six stratigraphic units.

The Late Ordovician submergence followed a weak uplift in the middle part of the Middle Ordovician, and corresponds to the widest known Palaeozoic advance of the Arctic seas. The cycle was probably terminated by positive movements which on adjacent Somerset Island culminated in the Early Devonian.

The Middle Ordovician interval of eastern North America displays a sedimentary sequence which was imprinted by the effects of the developing Taconic orogeny.

In central Pennsylvania this interval is a carbonate bank-to-basin transition. The lower part (Black River) can be divided into four paleoenvironmentally significant facies.

These carbonate breccias have been previously interpreted as intraformational or fault breccias. Thus, little attention has been focused on tectonic and stratigraphic significance of these breccias.

The burrows are abundant in red calcareous palaeosols, and were created by animals living at the time of soil formation, because they are filled with red sediment like that of the palaeosol matrix, and both cut.

The purest limestone in the lower Middle Ordovician of this area is light to medium "dove" gray, very dense to lithographic stone, called "vaughanite" (Kindle, ). Although it is distributed throughout this section, the vaughanite is most abundant and thickest in the upper part of the New Market Formation.

The Great Valley and nearby areas within south-central Pennsylvania (Franklin and Cumberland counties) were chosen based on the density of carbonate streams.
