A glacier is a perennial mass of ice which moves over land. A glacier forms in locations where the mass accumulation of snow and ice exceeds ablation over many years. The word glacier comes from F...

- nonsorted glacial drift deposited directly from ice. Till consists of a random mixture of different sized fragments of angular rocks in a matrix of fine grained, sand- to clay-sized fragments that were produced by abrasion within the glacier.

Topic 24: GLACIERS AND GLACIAL DRIFT A glacier is a large, long-lasting mass of ice found on land that mores because of gravity. The theory of glacial ages states that at times in the past, colder climates prevailed during which much more of the land surface of the earth was glaciated than at present.

Glacial drift is the general term applied to materials eroded from the surface and deposited by glaciers. Glaciers transport the embedded material towards the front of the glacier as if they were on a conveyor belt, or is deposit directly beneath the ice.

The ratio of purple to red garnet identifies drift provenance. Low ratios indicate glacier flow from the central Adirondacks. Ratios of 1.4 or greater indicate flow from Canada, by way of the St. Lawrence lowland.

Pebbles of pisolitic bauxite occur in Pleistocene drift on Martha's Vineyard. The bauxite contains plant remains and relict quartz and was derived from plant-bearing sediments, probably from the preglacial coastal plain of New England.
