“Diamicton is a descriptive term referring to a deposit that is usually massive and poorlysorted, containing clasts of many sizes. The clasts range in size from clay to boulders and are of varying compositions. The previous description sounds like a till, however the term diamictonshould be used when the origin of a deposit is not known. The term till implies a glacial origin and would therefore be inappropriate if the origin is nonglacial. The term glacial diamicton or till shouldonly be used when the origin of the deposit is known to be glacial.”
