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.
