The Carboniferous Limestone cropping out near Wellington and near Newport in the Wrekin district has hitherto received little attention. One or two references to the Lower Carboniferous rocks of the area are made in Geology in the Field, in which the limestone is referred to the Dibunophyllum zone, and the intrusive material underlying the limestone is described as an olivine-dolerite, probably of Tertiary age. Apart from these references there does not appear to be any published description of the limestone of the district. Although the Lower Carboniferous outcrops in the area are small, the faunal contents, stratigraphical horizon, and petrology of these rocks are subjects of interest in connection with recent work on the Carboniferous Limestone of various Midland districts.
