摘要: A theory of erosion, transport and deposition unlithified sediments by glaciers is presented. It predicts the large-scale areal distribution zones rates erosion in time space through a complete glacial cycle, together with resultant intensity lincations (drumlins) which will be incised landscape. The also dispersal patterns subglacial lithologies, form trains derived from distinctive sources vertical horizontal lithologies within till. major erosional discontinuities tills formation boulder pavements. suggests that dominant proportion lowland produced Pleistocene mid-latitude ice sheets was generated deformation explains why they are predominantly fine-grained. based on an analysis glacier-dynamic processes therefore can used to infer dynamic behaviour former their lithologic composition.
