melt-out till


melt-out till
   A till that may be either subglacial or supraglacial in origin. Melt-out till forms by slow melting of debris-rich stagnant ice, but without secondary flow processes. The fabric and clast orientations, imparted by ice processes, remain mostly intact.

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