The process sedimentology of tills is crucial to the understanding of the glacier ice–bed interface as a complex depositional, erosional and shear boundary layer. Consequently, it also plays a central role in deciphering the genesis of enigmatic subglacial bedforms such as drumlins, flutings and ribbed terrain. Yet, unlike the study of other boundary layers such as those that operate at the bed of fluvial, aeolian and deep water systems, our knowledge of subglacial process–formrelationships is relatively impoverished, largely due to the inaccessibility of glacier and ice sheet beds.

Wawa has long been a center of mineral exploration activity and diamonds have been reported in the area since the 1930s. However, diamond exploration did not begin in the area in earnest until 1991. In 1993, Sandor Surmacz and Marcelle Hauseux of Saminex began a prospecting program in the area which culminated in their discovery of the “Sandor” diamond occurrence in an outcrop on the east side of the Trans-Canada Highway.

Рассмотрены полевые и лабораторные методы изучения ледниковых и сходных с ними отложений. Особый упор сделан на детальные полевые исследования и формационный анализ. Предложены диагностические таблицы для основных разновидностей тиллитов: континентальных и бассейновых. Руководство направлено на диагностику ледниковых отложений и последующую более детальную стратиграфическую, фациальную и палеогеографическую их интерпретацию. Работа рассчитана на геологов, изучающих ледниковые и сходные с ними отложения, палеогеографию, палеоклиматологию, региональную геологию
