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 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 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 Carboniferous (/ ˌ k ɑːr b ə ˈ n ɪ f ər ə s / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic era that spans 60 million years from the end of the Devonian Period 358.86 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma.
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 exact age of these rocks is uncertain but ranges from the late Devonian into the early Carboniferous. They have been assigned both to the Upper Old Red Sandstone Group and to the Ravenstonedale Group at different times. An early Devonian intrusion of dolerite or microgabbro occurs at Bluecaster to the northwest of Cautley.
The majority of the solid rocks of Cheshire are sedimentary rocks laid down during the Permian and Triassic periods. Both the east and west Cheshire Plains are immediately underlain by Triassic sandstones, siltstones and mudstones, although outcrops are restricted to those areas that are not covered by thick expanses of glacial till of glacio-fluvial sands and gravels, such as the Mid Cheshire ...
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.
