The classic unconformity section exposed in quarries at Vallis Vale was described by Sir Henry de la Beche in the world's first geological survey memoir in 1846. Another early scientist was Charles Moore who in the 1850s and 60s, examined the quarries at Holwell where he found deep fissures in the Carboniferous Limestone infilled with younger

The disused Asham Wood and Westdown Quarries in the Leighton valley clearly expose the lower part of the Black Rock Limestone. The thinly bedded, muddy limestones here are weak and easily folded, and several excellent, highly contorted, fold structures can be seen in Asham Wood Quarry.

British Geological Survey Internal Report, Both hard rock and sand and gravel resources have been quarried until relatively recently, but currently there is no such activity. Large former workings include the quarries in the Huntly Pluton in the Bin Forest [NJ 498 431] and at Battle Hill [NJ 539 395].
The Blue Lias is a geological formation in southern, eastern and western England and parts of South Wales, part of the Lias Group.The Blue Lias consists of a sequence of limestone and shale layers, laid down in latest Triassic and early Jurassic times, between 195 and 200 million years ago. The Blue Lias is famous for its fossils, especially ammonites.. Its age corresponds to the Rhaetian to

Hard wacke sandstone within the Silurian Kirkby Moor Formation has very high polished stone values and is quarried for roadstone at Holmscales and Roan Edge, near Kendal. The quartz arenite-dominated Creg Agneash Formation in the Ordovician Manx Group is today worked for crushed rock aggregate at Dreemskerry on the Isle of Man.
Nov 21, 2016· Quarrying and mining have played a fundamental role in the development of society over the last 2 million years. In addition, it generates information and specimens that support the advancement of geoscience and creates exposures that provide a resource for scientific study, education, training and geotourism; a resource that would not otherwise exist.
Mar 06, 2011· Gardiners Quarry is one of many aggregates quarries that can be found across the Malvern Hills. Found on the western side of the hills, it is a small quarry; 30m across and 15m high. Currently the quarry is used as a Malvern Hills Conservators car park, as it one of the main points of access to the hills above.
The Stiperstones are made up of quartzite and like the Wrekin Quartzite is a misnomer as it is a hard, white sandstone and not a metamorphic rock (like true quartzite is). The Stiperstones have the added advantage that besides the Ordovician rock, you also have the tors formed from millennia of ice/frost shattering. Cambrian (542ma to 488ma)

Allington Quarry is a Site of Special Scientific Interest (SSSI) as the result of interesting geological features uncovered as a result of quarrying. Once sand and ragstone quarrying had ceased, the quarry became the site of the Allington Quarry Waste Management Facility.. Allington was an attractive site for ragstone quarrying on account of its geology and close proximity to the River Medway
