A revised stratigraphy of the Malvern, Abberley and Ledbury Hills is given. The Silurian succession is considered in detail and shows a series of five major sedimentary rhythms or cycles between an initial Llandovery transgression and regression at the close of the Silurian period. The succession exhibits an alternation of shale with either limestones and/or terrigenous clastics, and the rhythmic nature of the sequence suggests a periodic change in base level. A number of different lithological facies can be distinguished in the limestone formations, particularly in the Wenlock limestone. A detailed faunal list is given for most of the Silurian sequence. From the evidence of the stratigraphic succession, an attempt has been made to decipher the complex geological history of the area.
