Devonian and Carboniferous stratigraphical correlation and interpretation in the Central North Sea, Quadrants 25 – 44

This report details the stratigraphy and palaeogeography of Devonian and Carboniferous rocks of the UK Central North Sea for the 21CXRM Palaeozoic project. The 21CXRM Palaeozoic project results are delivered as a series of reports and digital datasets for each area. This report describes the stratigraphical correlation of Devonian and Carboniferous strata south of, and over, the Mid North Sea High (Quadrants 25-44) using both well and seismic data. It builds on the work of Cameron (1993a) and others, and uses lithostratigraphy to understand how facies vary across the area. A major outcome of this work is the detailed description of the Cleveland Group, the basinal correlative of the Scremerston, Yoredale and Millstone Grit formations within the offshore extension of the Cleveland Basin.
