Each of the major stratigraphic units in this sequence, namely the Pendle and Grassington Grit Groups, represents a phase of clastic input to the …

Stratigraphy of the mid-Carboniferous boundary
… of the Clare Basin were flooded during the early Namurian leading to an environment suitable for phosphate authigenesis. During a major regression in the Pendleian/lower Arnsbergian the phosphate was reworked into a lag. The lowstand of the basal Chokierian is marked by a thin lag on the shelves, …
