The Late-Quaternary deposits of the middle Dyfi Valley,Wales
Authors:G S P Thomas  A J Summers  R V Dackombe
Abstract:The surficial deposits and landforms of the middle Dyfi Valley, Wales, are examined and a sequence of glacial, glacio-fluvial and glacio-lacustrine sediments is identified. This is considered to relate to a late stage in the wastage of the Late-Devensian Merioneth ice-cap. A sequence of terrace gravels overlying the giacigenic succession represents dissection during early Flandrian times.
Keywords:Quaternary  Wales  Frost structures  Glaciation  River terraces  Seismic methods
