Abstract
Glaciation has left a strong imprint on development of the coast in eastern Canada. Postglacial changes in relative sea level have varied widely across the region, exerting a major control on shoreline migration and tidal range. Glacigenic deposits are the major sources of sediment supply to the coastal zone in most parts of the region. These sources include extensive thin covers of ground moraine, major drumlin fields, and localized deposits of ice-contact, glaciomarine, and glaciofluvial sediments. The widespread occurrence of gravel beaches in glaciated areas can be attributed in part to high proportions of coarse clastic material in glacigenic sediments. Case studies presented in this chapter include sand-gravel and gravel beaches on the exposed sediment-deficient coast of southern Newfoundland, on the drumlin coast of southeast Cape Breton Island, and in the macrotidal Bay of Fundy. These examples illustrate the role of various geological and environmental factors in the shaping of beach morphology and facies characteristics.
