Middridge Quarry
Middridge Quarry is a Site of Special Scientific Interest in the Sedgefield district of County Durham, England. It is a disused quarry, situated alongside the railway line between Newton Aycliffe and Shildon, 1 km south of the village of Middridge. The quarry was excavated in Magnesian Limestone, the lowest level of which is an exceptionally fossiliferous marl slate which has yielded the richest and most varied Permian flora in the Britain and is the type locality for the pteridosperm The term Pteridospermatophyta (or "seed ferns" or "Pteridospermatopsida") is a polyphyletic group of extinct seed-bearing plants (spermatophytes). The earliest fossil evidence for plants of this type is the genus ''Elkinsia'' of the late Devonian ... ''Pseudoctensis middridgensis''. Fossils obtained from the quarry have included several species of fish and reptiles, numerous invertebrates and plants, and the site is considered to be of international palaeontological importance.

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Sedgefield (district)
Sedgefield District was, from 1974 to 2009, a local government district and (from 1996), borough in County Durham, in North East England. It had a population of about 87,000 (2001 UK census). It was named after Sedgefield, but its largest town was Newton Aycliffe. Other places included Shildon, Ferryhill and Spennymoor. The borough was formed (as Sedgefield District), in 1974, under the Local Government Act 1972, by the merger of Sedgefield Rural District, Spennymoor and Shildon urban districts and part of Darlington Rural District. The borough was abolished as part of the 2009 structural changes to local government in England. From 1983 to 2007, most of the district was represented in parliament by Tony Blair, who became Leader of the Labour Party in 1994, and Prime Minister A prime minister, premier or chief of cabinet is the head of the cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential syste ...

Shildon
Shildon is a town and civil parish in County Durham (district), County Durham, in England. The population taken at the 2011 Census was 9,976. The town has the Locomotion Museum, due to it having the first , built in 1825, and locomotive works on the Stockton and Darlington Railway. History The name Shildon comes from the Old English word ''sceld'', This translates as 'shelf shaped hill' or 'shield/refuge'. Another possibility is the Old English word ''syclfe'' meaning 'shelf' and the suffix ''duri'' meaning 'hill'. This refers to the town's location on a limestone escarpment.Shildon County Durham Conservation Area Prepared for Sedgefield Borough Council Conservation Area Character Appraisal December 2008 ''Report No: 0055/1-08'' Report by Archaeo-Environment Ltd The earliest inhabitants of the area were most likely present from the Mesolithic period some 6,000 years ago.

Middridge
Middridge is a village in County Durham, North East England. It is situated east of Shildon and north-west of Newton Aycliffe. The village is situated near a quarry that was mined by the people many generations ago. There is one public house in the village: the Bay Horse. History Following the fall of the Roman Empire, the Angles arrived in the area around 500 AD and created several settlements, including Middridge. The name "Middridge" is derived from its location at that time on the "middle ridge" between Eldon and School Aycliffe (near the current Aycliffe golf course). Anglo-Saxon Middridge lasted for five hundred years before being destroyed by the Normans during William the Conqueror's Harrying of the North. Those who survived this massacre (and the resulting disease and starvation) were enslaved by the invaders. They were forced by the Bishop of Durham to toil in the surrounding fields as serfs, and forcibly relocated to gloomy huts centred on the village green. The " ...

Magnesian Limestone
The Magnesian Limestone is a suite of carbonate rocks in north-east England dating from the Permian period. The outcrop stretches from Nottingham northwards through Yorkshire and into County Durham where it is exposed along the coast between Hartlepool and South Shields. The term has now been discontinued in formal use though it appears widely in popular and scientific literature on the geology of northern England. The Magnesian Limestone is now incorporated within the Zechstein Group. In the southern part of its outcrop, the former 'Lower Magnesian Limestone' is now referred to as the 'Cadeby Formation'. Overlying this it is the 'Edlington Formation' (formerly the 'Middle Permian Marl') and above this the Brotherton Formation (formerly the 'Upper Magnesian Limestone'). In the north, the Lower Magnesian Limestone is now referred to as the Raisby Formation and the middle Magnesian Limestone as the Ford Formation. The Upper Magnesian Limestone is replaced by the Roker Formation (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for ex ...

Pteridosperm
The term Pteridospermatophyta (or "seed ferns" or "Pteridospermatopsida") is a polyphyletic group of extinct seed-bearing plants (spermatophytes). The earliest fossil evidence for plants of this type is the genus ''Elkinsia'' of the late Devonian age. They flourished particularly during the Carboniferous and Permian periods. Pteridosperms declined during the Mesozoic Era and had mostly disappeared by the end of the Cretaceous Period, though some pteridosperm-like plants seem to have survived into Eocene times, based on fossil finds in Tasmania. With regard to the enduring utility of this division, many palaeobotanists still use the pteridosperm grouping in an informal sense to refer to the seed plants that are not angiosperms, coniferoids (conifers or cordaites), ginkgophytes or cycadophytes (cycads or bennettites). This is particularly useful for extinct seed plant groups whose systematic relationships remain speculative, as they can be classified as pteridosperms with no va ...
