Definition of Wolstonian in English:



  • 1Relating to or denoting the penultimate Pleistocene glaciation in Britain, identified with the Saale of northern Europe (and perhaps the Riss of the Alps).

    • ‘The Wolstonian loess is mineralogically different from the Devensian, but it has been more strongly weathered and its origin is uncertain.’
    • ‘The drift sequences in Northamptonshire are usually attributed to the Wolstonian glacial cycle, as the county lay some distance south of the maximum advance of the Devensian ice sheets.’
    • ‘It is uncertain whether the ice during the Wolstonian stage affected the region.’
    • ‘This trough subsequently formed a lake basin which filled with sediment during the entire interglacial and part of the ensuing Wolstonian glacial stage.’
    • ‘Scourse therefore suggested that the sequence might be attributable to sediments deposited at the end of an interglacial, or possibly during an interstadial within the Wolstonian cold stage.’
    1. 1.1as noun the Wolstonian The Wolstonian glaciation or the system of deposits laid down during it.
