flow till


flow till
   A till that may be either subglacial or supraglacial in origin. Flow till displays secondary transport, sorting, and/or fabric modification by plastic mass flow. Flow till exhibits weak stratification and sorting and may contain distorted layers indicative of lateral displacement and soft sediment deformation. The secondary flow processes obliterate most of the original fabric and clast orientations in the till.

  • supraglacial till —    Till deposited on top of or within the upper part of a glacier or ice sheet.
