Further to my earlier post about the exposures now to be seen at Ceibwr, here are some more photos, from the flanks of the rocky spur that separates Channel 1 from Channel 2. Again, no complete sequence is to be seen, but at the northern tip of the spur we can again see TWO tills of different ages, one of them solidly cemented and the other fresh, separated by stained and bedded gravels:
River cutting upstream from the footbridge, in the main Ceibwr valley. Cemented foxy-red gravels are seen here beneath blue-grey till with abundant clasts derived from local slope breccias.
Modern soil -- c 20 cms. Uncemented
Sandloess and colluvium -- c 50 cms. Uncemented. Holocene?
Clay-rich Irish Sea Till -- up to 2 m thick. Blue-grey colour. Uncemented. Late Devensian?
Brecciated slope deposits -- up to 50 cms thick. Uncemented. Early / Middle Devensian?
Clay-rich colluvium -- c 20 cms thick. Uncemented but stained / gleyed. Ipswichian interglacial?
Glaciofluvial gravels -- c 1.5m thick. Stained and cemented. Foxy red colour. Anglian?
Stony till -- up to 1m thick. Stained and cemented by iron oxide and manganese oxide precipitates. Foxy red / purple / black colouring. Anglian?
Brecciated slope deposits -- up to 1 m thick. A pre-glacial Anglian phase?
