This guide is a starting point for exploring the geology of the Pennines between the southern Yorkshire Dales and Nidderdale in the north and the southern part of the Derbyshire Peak District in the south. The book concentrates on the main Pennine range, but also takes in higher ground to the west, including Rossendale, the Forest of Bowland and the Staffordshire Moorlands. While the guide is aimed primarily at undergraduate level, it is written and illustrated to also appeal to visitors to the area. The greater part of the guide deals with sedimentary rocks of Carboniferous age (360-300 Ma). It discusses the changing tectonic regime and its influence on the development of sedimentary basins and their sedimentation. It describes the depositional environments, the subsequent tectonic deformation of the sediments and the controls on present-day outcrop patterns. The older visible geology consists mostly of limestones, deposited in a tropical setting during the Dinantian (360-330 Ma) on s
