The laying down of sediments which have been removed and transported by a glacier (see Larson and Piotrowski (2005) J. Sediment. Res. 75). The sediments—known as till, or drift—are deposited when the ice melts; when ablation is dominant. Glacial deposition is predominant in marginal areas of present and past ice sheets, such as the Eden Valley, and much of the English Midlands, but also occurs in uplands, especially in the form of moraines. See Escutia et al. in Cooper and Raymond et al. (2007) Online Procs 10th ISAES on meltwater production and high sediment discharge in the East Antarctic.
