Carreg Cennen Disturbance : ウィキペディア英語版 | Carreg Cennen Disturbance The Carreg Cennen Disturbance is a zone of geological faults and folds in south and mid Wales which forms a part of both the Church Stretton Fault Zone and the Welsh Borderland Fault System. To the southwest it is known as the 'Llandyfaelog Disturbance'.〔British Geological Survey 1:50,000 map sheets 229 'Carmarthen' & 230 'Ammanford'〕 These structures which stretch from Pembrokeshire to Shropshire are thought to have originated during the Caledonian Orogeny or mountain-building period. ==Influence on the landscape==
It is most impressively revealed at Carreg Cennen 〔http://www.geograph.org.uk/search.php?i=4967683 images of Carreg Cennen on Geograph website〕 itself where the mediaeval castle sits perched atop a 90m cliff of Carboniferous Limestone which is caught up within a faulted block sitting between two arms of the Disturbance. It is probably also responsible for the alignment of the Afon Cennen to the west of this location where the river follows the line of the fault for over 2.5 mi / 4 km.
