The existing lithostratigraphic nomenclature of the late Carboniferous succession of Staffordshire and Shropshire is reviewed in the light of boreholes drilled since 1950. Four lithostratigrahic units are recognized on the basis of sandstone composition, assemblages of detrital clay minerals and geophysical log response. A regionally developed lithostratigraphic marker formed by a palustrine sequence with a distinctive gamma ray response is identified. Recognition of these features permits the identification of former incorrect correlations, and allows revisions to the lithostratigraphy to be proposed. A revision of the macroflora indicates a late Westphalian D to Cantabrian age for the higher part of the succession. © 1997 John Wiley & Sons, Ltd.
