Although more detailed till classifications have been proposed (Boulton, 1968; 1970) Ablation of the SRB occurs when ice on the surface melts or is sublimated. Lodgement till forms as a sheet of well-compacted sediment beneath a glacier, and ranges from several centimeters to many meters in thickness. Till generally can be divided into two categories: lodgement and ablation. What Is Till In Science - Realonomics Note the wide range of particle size. Angular Template Variables, PDF Soil Parent Materials of Rhode Island Lodgement till is compacted and may acquire a fissile structure; crushing and abrasion of particles are considerable.

Ablation till accumulates initially in a supraglacial position and is later lowered to the ground surface by undermelting. In situations where a glacier is receding, a block of ice might become separated from the main ice sheet and become buried in glaciofluvial sediments.
