The British Geological Survey (BGS) is a partly publicly funded body which aims to advance geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research. The BGS headquarters are in Keyworth, Nottinghamshire, England.
The geology of the Peak District National Park in England is dominated by a thick succession of faulted and folded sedimentary rocks of Carboniferous age. The Peak District is often divided into a southerly White Peak where Carboniferous Limestone outcrops and a northerly Dark Peak where the overlying succession of sandstones and mudstones dominate the landscape.
BGS Groundhog Desktop is a software tool developed and made available by the British Geological Survey and used for geological data visualisation, interpretation and 3D geologic modelling. It is available in both free-to-use and commercial editions. Groundhog Desktop is a key part of the BGS's work to develop 3D models of the UK subsurface. [1]
The British Geological Survey map numerous residual deposits across the upper surfaces of the South Downs, derived from the solution, decalcification and cryoturbation of the underlying bedrock. Referred to as the Clay-with-flints Formation, the deposit also contains sand and silt in places.
The Afon Cilieni is a short river which rises on the southern slopes of Mynydd Epynt in Powys, Wales.The name may mean ' the river rising in a small nook'. [1]Its upper reaches are within the military training area of SENTA, the British Army's Sennybridge Training Area.
Panorama of part of the Snowdon Massif including Snowdon (centre right) taken from Mynydd Mawr.The Glyderau are visible in the distance.. The bedrock geology of Snowdonia is largely formed from a sequence of sedimentary and igneous rocks originating during the early Palaeozoic (the Cambrian, Ordovician and Silurian periods, lasting between 539 and 419 million years ago).
The geology of the Yorkshire Dales National Park in northern England largely consists of a sequence of sedimentary rocks of Ordovician to Permian age. The core area of the Yorkshire Dales is formed from a layer-cake of limestones, sandstones and mudstones laid down during the Carboniferous period.
Silurian rocks are found in the northwest of the park where a north-east to south-west aligned tract of country running (within the park) from Halfway southwest to Trap is known to geologists as the Myddfai Steep Belt and formed from a succession of sandstones and mudstones of Wenlockian, Ludlovian and Pridoli age.
