Summary This investigation shows the complexity of soil materials which will arise in many similar areas due to the combined influence of underlying rock, local ice movement, far‐travelled ice, and wind transportation, and its elucidation has been attempted on the basis of a comprehensive knowledge of the mineralogy of the regional soils, geological strata, and superficial deposits. The criteria for recognizing the presence of wind‐blown materials (by sorting according to specific gravity) are discussed. The DyfFryn series is essentially formed on a local drift produced by ice that moved off the Coalfield and traversed the Vale of Glamorgan, this ice also influencing otherwise sedentary soils of the Sand Hall, Cogan, and Worcester series; the Ston Easton series includes soils deriving much of their content from the underlying rock, but some from the Irish Sea Drift and some blown by winds off the coastal sands; and the Gower soils and Sully phase arc influenced chiefly by the underlying rock but also by wind‐blown material. In some places the Gower series is influenced by the Irish Sea Drift which attains its maximum effect in the Gower Peninsula.
