The Lower Greensand as a broad zone between the brick-patterned chalk (a type of limestone) and the interior large c-shape Weald Clay. Many towns shown are on the Lower Greensand. The Lower Greensand Group is a geological unit present across large areas of Southern England. It was deposited during the Aptian and Albian ages of the Early ...

Geology The White Peak area of the Peak District is named after the limestone plateau landscape of the ' Derbyshire Dome '. This limestone outcrop is surrounded by a horseshoe ...
The formation of Carboniferous Limestone was followed by the deposition of dark marine shales, siltstones and coarse sandstones of the Millstone Grit, notably in the area later uplifted to form the Pennine anticline. This sequence can be seen in the Yorkshire Dales with Ingleborough protruding up above the Carboniferous Limestone landscape below.
The Great Oolite Group is a Middle Jurassic stratigraphic unit that outcrops in southern England. It consists of a complex set of marine deposits primarily mudstone and bioclastic ooidal and fine grained limestone, deposited in nearshore to shelf settings. [1]
Locally sourced limestone has been used in the construction of the castles at Carew, Manorbier and Pembroke. Significant coastal limestone quarries were also active at Lydstep and Caldey. [10] Slate was quarried at Caersalem Quarry at Porthgain and exported via the village harbour. Many older buildings and field walls have been constructed from ...
Horton Quarry is a limestone quarry near to Horton-in-Ribblesdale, North Yorkshire, England. The quarry, which is some 6 miles (9.7 km) north of Settle, has been operating since at least 1889, and produces limestone for a variety of purposes. Stone used to be exported from the quarry by rail, but now leaves by lorry, although there are plans to ...
The quarry's rocky slopes, grassy pockets and sheltered gullies are all havens for wildlife, and therefore features a wide range of plants and animals, hosting flora and fauna specific to limestone soil. [7] Described as one of Portland's prime nature habitats, [8] the thin limestone soils have been slowly colonised by a variety of wildflowers ...
Kentish ragstone is a hard grey limestone in Kent, England, drawn from the geological sequence known as the Hythe Beds of the Lower Greensand. For millennia it has been quarried for use both locally and further afield.
