Here the base is taken at the sharp erosional contact between the oolitic grainstones of the Gully Oolite Formation and the overlying coarse skeletal packstone/grainstones of the Formation. In the southern parts of the Welsh outcrop, the Formation overlies the Gully Oolite Formation. A basaltic lava is present in the lower part of the sequence in the Weston-super-Mare area. The base is taken at the sharp erosional contact between the thin-bedded calcite mudstones and the mudstones of the underlying Caswell Bay Mudstone Formation and the overlying coarse peloidal/skeletal/oolitic packstone/grainstones forming the lower part of the Formation in South Wales and the Weston-super-Mare areas. On the southeast crop of the South Wales Coalfield the Formation is predominantly dolomitized.

Coarse, locally cross bedded, peloidal/skeletal/oolitic packstones/grainstones developed in lower and upper parts in northern sections. Some thin-bedded dark grey bituminous skeletal packstones interbedded with thin argallaceous wackestones and mudstones. Mid grey, predominantly thick-bedded, fine- to coarse-grained, burrowed, skeletal packstones, with thin beds and partings of shaly dolomite mudstone and siltstone.
