A correlation of the Zechstein strata of England and Germany is presented. It is based on strong similarities in the distribution, thickness and lithology (including lithological succession) of the various evaporites in the two sequences and, particularly, on an upwards change in colour from mainly grey to mainly red between the second and third cycles; this change probably indicates a basin-wide change in the oxidation state of the Zechstein Sea. By these criteria, it is suggested that strata of the Don and Aislaby groups of England together are equivalent to the deposits of the Werra Cycle in Germany and that those of the Teesside Group are correlatives of the German Stassfurt sequence.
