对马尔文、阿伯利和莱德伯里山的地层进行了订正。志留纪序列被认为是详细的，并显示了一系列的五个主要的沉积韵律或周期之间的初始Llandovery海侵和海退在志留纪结束。该序列表现出页岩与石灰岩和/或陆源碎屑岩的交替，序列的韵律性表明基准面的周期性变化。在石灰岩地层中可以区分出许多不同的岩相，特别是在温洛克石灰岩中。文中给出了志留纪大部分层序的详细动物群列表。根据地层序列的证据，人们试图解释该地区复杂的地质历史。
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.
