The formation is made up of three different members which have been classified as the Lower Quarried Limestone Member, the Nodular Beds Member and the Upper Quarried Limestone Member.<ref>Dorning, K. J. 1983. Palynology and stratigraphy of the Much Wenlock Limestone Formation, Dudley, Central England. Mercian Geologist, 20, 31-40.</ref> Many of the members can be subdivided into separate lithofacies that would have been deposited under different environmental conditions. However the overall environment of deposition for the formation is in a shallow, tropical marine setting that is located between the storm wave base and the fair weather wave base.
