| 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. |
