UK Stratigraphical Framework Series : the Ancholme Group of the East Midlands shelf

This report forms part of the UK Stratigraphical Framework Series (UKSFS) and provides an overview of the stratigraphy of the Ancholme Group (combined Kellaways Formation, Oxford Clay Formation, West Walton Formation, Ampthill Clay Formation, Kimmeridge Clay Formation) of the East Midlands Shelf. The work is based on interpretation of borehole geophysical logs and published records of cored boreholes. The emphasis of the report is on establishing criteria that allow the confident subdivision of the Ancholme Group (a predominately marine mudrock succession) into its component parts.
