Characteristics of ice-wedge casts in west central Wales

Auteur :
WATSON, E.

Description :
Most of the wedge casts occur in angular slope gravel, fluvial or fluvio-glacial gravels, the largest reaching a width of 2-3 m and a depth of 3-5 m. Upturning of the host gravel occurs, especially with the larger casts. Slump or sag structures in the fill are limited to platy gravels| in other gravels, the wedge fill is characterized by very steeply dipping clasts. Though no means of precise dating is available, it is throught that the wedge casts formed in the later part of the last glaciation.
