Definition of Wolstonian in US 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.’
    • ‘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.’
    • ‘It is uncertain whether the ice during the Wolstonian stage affected the region.’
    • ‘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.’
    • ‘This trough subsequently formed a lake basin which filled with sediment during the entire interglacial and part of the ensuing Wolstonian glacial stage.’
