ABSTRACT
Glaciers, the producers of glacigenic sediment, derive their debris from bedrock or by recycling older sediment that, in turn, has also been derived from bedrock. Quantitative lithologic and geochemical investigation of till, and a comparison with the bedrock lithology in the upglacier area, will assist in the determination of the regional ice flow direction and in finding the possible provenance area of the ore fragments. Several types of glaciers are distinguished, according to their morphologic form and relation to the topography. An ice sheet is independent in its general form from the underlying topography, and the glacial movement is determined mainly by its surface gradients. The Scottish term ‘till’ is the most popular name for glacial sediment in the English language and it is gradually invading the scientific terminology of other languages. Till is a diamicton that has been transported and is subsequently deposited by or from glacier ice, with little or no sorting by water.
