Abstract/Summary

Three sets of syn-sedimentary slides affecting delta deposits of the Ashover Grit have been identified in the area south and east of Wirksworth, Derbyshire, UK. The kilometre-scale slide masses, which are expressed clearly in the landscape, consist of arrays of fault blocks tilted back towards listric fault surfaces that sole out into underlying basinal mudstone. Relationships in one of the slide arrays, at Black Rock, suggest that the movements took place during the later stages of delta advance. There is a possibility that some minor compressional structures exposed in surface sections away from the fault blocks are also related to syndepositional movements.
