โฆ Synopsis
The rock types and successions encountered at two localities have been described and interpretated with reference to modern analogues. In the Clifton Down Limestone a cycle of sedimentation is recognised passing from intertidal algal mats, through lagoons, barrier and open shelf deposits and back through the same sequence to intertidal algal mats.

The successions were measured and samples (approximately 400 samples) were collected from nearly every unit. In the laboratory the limestone samples were cut, polished, etched with 1-75 % HC1 and stained with Alazarin Red S and potassium ferricyanide in 1.75 % HCl solution (Davies and Till 1968). An acetate peel of the dry stained surface was prepared for examination under the microscope.
The limestones have been described according to the classification proposed by Folk (1959,1962).

A laminated and slumped limestone bed from the Carboniferous Limestone of Derbyshire, known as the Rosewood Marble, is described in detail. The laminations comprise alternations of micrite and dolomite, the dolomite laminae originally being fine grainstones. The bed was deposited on a slope and slip
This investigation of previously undescribed country along the Staffordshire-Derbyshire border indicated the need for reexamination of adjoining areas described in 1950 and 1951. The main revisions concern the ages of certain beds and the nature of the unconformities. Evidence is adduced of vertical
