Sutton stone has always been highly regarded: as well as being used in construction throughout the Vale of Glamorgan, it was also shipped over the Bristol Channel to North Devon and North Cornwall, which are both deficient in limestone. A major geological feature of the Upper Carboniferous rocks in south Wales is the south Wales coalfield. The ...
The sea cliffs of the Pembrokeshire coast provide numerous venues for rock climbing, particularly on the Carboniferous Limestone in the south and the igneous rocks of the north coast. Coasteering is a sport which has grown popular around the coast of the National Park in recent years which makes use of the abundant coastal cliffs.
The north east of Cornwall lies on Carboniferous rocks known as the Culm Measures. In places these have been subjected to severe folding, as can be seen on the north coast [ 2 ] near Crackington Haven , spectacularly at the Whaleback Pericline on the beach just south of Bude and at several other locations.
The peninsula is formed almost entirely from a faulted and folded sequence of Carboniferous rocks though both the earlier Old Red Sandstone and later New Red Sandstone are also present. Gower lay on the southern margin of the last ice sheet and has been a focus of interest for researchers and students in that respect too. Cave development and ...
In Southern England, the Jurassic rocks are subdivided upwards as the Lias, Inferior Oolite, Great Oolite, Ancholme (interfingering with Corallian) and Portland groups. These rock units include sandstones, greensands, oolitic limestone of the Cotswold Hills, corallian limestone of the Vale of White Horse and the Isle of Portland.
Triassic rocks provided the Radyr stone and also the Quarella stone which was worked at Bridgend. [10] Sutton Stone from South Wales' Jurassic outcrop is a highly regarded limestone freestone that has been used in construction throughout the Vale of Glamorgan, it was also shipped over the Bristol Channel to North Devon and North Cornwall which ...
The Carboniferous coals are overlain by Permian and Triassic sediments. [4] The sediments were uplifted and faulted within the Variscan Orogeny , with the land now occupied by East Sussex being a low external fold belt to the main orogeny, which was located within the present day English Channel , [ 5 ] the remnants of the mountain belt can be ...
The youngest rocks are in the south east around London, progressing in age in a north westerly direction. [1] The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to higher relief in those regions.
