A stratigraphical framework for the Upper Langsettian and Duckmantian of the East Pennine coalfields

This report describes the stratigraphy of named coal seams and sandbodies in that part of the Coal Measures Group which forms the principal productive measures of the East Midlands coalfields (Upper Langsettian and Duckmantian). Coal seams are combined into ‘groups’, which describe the general association of a number of coal seams rather than formal stratigraphical units. For each seam, preferred nomenclature and known alternatives are presented together with descriptions of the correlations. Sandbodies are described in terns of their position with respect to the established coal seam stratigraphy. A diagrammatic correlation panel, which summarizes the relationships described, is appended.
