Statement

Developed from the pre-existing DIC_CHRONOSTRAT, parts of which had become obsolete. The development followed the recommendations of the BGS Stratigraphy Committee. DIC_CHRONOSTRAT was itself developed from a pre-existing digital chronostratigraphical index which formed segment CSCO of BGS.DIC.
