Stratigraphy and properties of the clyde alluvium

The paper outlines the geological history of the Clyde Valley and attempts to relate this to the nature and distribution of the sediments within it. Because of the position of the valley within a glaciated region in which isostatic recovery has occurred, the infill deposits are very complex, with fluvio-glacial, lacustrine, marine, brackish and freshwater deposits overlying glacial and pre-glacial materials. The soils within the succession have been identified, classified in terms of their basic physical properties and their likely engineering behaviours have been indicated. The engineering significance of the nature of the various strata within the stratigraphical sequence is then discussed.
