δ13Ccarb data from the Tortworth and Woolhope inliers, Midland Platform, UK, provide a record of part of the early Sheinwoodian (Ireviken) carbon isotope excursion. The shallow-marine mixed carbonate/siliciclastic successions exhibit a maximum δ13Ccarb value of +5.8‰ VPDB. Values begin to increase sharply at the Pycnactis Band, a prominent flooding surface, and decrease over a transgressive sequence between the Woolhope and Coalbrookdale formations. The study provides an improved chronostratigraphic correlation across the Sheinwoodian of the Midland Platform (Avalonia) and further afield, and highlights the power of integrated chemostratigraphy and sequence stratigraphy in the absence of well-developed biostratigraphy.
