After deposition . Till can be composed of a variety of particle sizes from clay-sized up to large boulders. The zone of ablation is where loss of ice mass is greater than accumulation. Lodgement till is compacted and may acquire a fissile structure; crushing and abrasion of particles are considerable. A(M0TA3 The finer particles of the upper till are commonly washed away by meltwater from the glacier and deposited in lacustrine and marine environments. ablation till vs lodgement till Login Using This Form ablation till vs lodgement till manage somehow - crossword The latter references materials deposited by glacial meltwater. Basal or lodgement till is compact and contains a greater amount of fine-grained sediment. When the ice block eventually melts, a depression forms, known as a kettle, and if this fills with water, it is known as a kettle lake (Figure 16.33).
