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 The Guadalupian is the second and middle series/epoch of the Permian. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains of New Mexico and Texas, and dates between 272.95 ± 0. ...

Cliffs Of Magnesian Limestone, Grangetown Promenade - Geograph
In geography and geology, a cliff or rock face is an area of Rock (geology), rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and Dolomite (rock), dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may ...

Zechstein Group
The Zechstein (German either from ''mine stone'' or ''tough stone'') is a unit of sedimentary rock layers of Late Permian (Lopingian) age located in the European Permian Basin which stretches from the east coast of England to northern Poland. The name Zechstein was formerly also used as a unit of time in the geologic timescale, but nowadays it is only used for the corresponding sedimentary deposits in Europe. The Zechstein lies on top of the Rotliegend; on top of the Zechstein is the Buntsandstein or Bunter. The Zechstein is associated with the accumulation of large amounts of salt rock between 257.3 and 251.0 million years ago. Formation The evaporite rocks of the Zechstein formation were laid down by the Zechstein Sea, an epicontinental or epeiric sea that existed in the Guadalupian and Lopingian epochs of the Permian period. The Zechstein Sea occupied the region of what is now the North Sea, plus lowland areas of Britain and the north European plain through Germany and Pola ...

Charles Hutton
Charles Hutton FRS FRSE LLD (14 August 1737 – 27 January 1823) was an English mathematician and surveyor. He was professor of mathematics at the Royal Military Academy, Woolwich from 1773 to 1807. He is remembered for his calculation of the density of the earth from Nevil Maskelyne's measurements collected during the Schiehallion experiment. Life Hutton was born on Percy Street in Newcastle upon Tyne in the north of England, the son of a superintendent of mines, who died when he was still very young. He was educated at a school at Jesmond, kept by Mr Ivison, an Anglican clergyman. There is reason to believe, on the evidence of two pay-bills, that for a short time in 1755 and 1756 Hutton worked in the colliery at Old Long Benton. Following Ivison's promotion to a church living, Hutton took over the Jesmond school, which, in consequence of his increasing number of pupils, he relocated to nearby Stotes Hall, since demolished. While he taught during the day at Stotes Hall, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnesia (regional Unit)
Magnesia (, ''Magnisía'', , Ancient Greek: ''Magnēsía'', deriving from the tribe name ''Magnetes'') is one of the regional units of Greece. It is part of the modern regions of Greece, region of Thessaly. Its capital is the city of Volos. About 70% of the population of Magnesia live in the Greater Volos area, which is the second-largest city in Thessaly and the third busiest commercial port in Greece. According to the most recent census (2021), the population stands at 177,448. The regional unit hosts 2,000,000 tourists annually. Magnesia is represented in the Greek Parliament by six seats. Its main agricultural products are wheat, cotton, tomatoes, grapes, olives, apples and honey. Geography A prominent geographic feature of Magnesia is the Pagasetic Gulf, a bay of the Aegean Sea. The Pelion mountain range closes off the Gulf on the east and south side, leaving only a narrow channel near Trikeri. The highest peak of the wooded Pelion is ''Pourianos Stavros'' or ''Xeforti'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refractory Brick
In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. They are inorganic, non-metallic compounds that may be porous or non-porous, and their crystallinity varies widely: they may be crystalline, polycrystalline, amorphous, or composite. They are typically composed of oxides, carbides or nitrides of the following elements: silicon, aluminium, magnesium, calcium, boron, chromium and zirconium. Many refractories are ceramics, but some such as graphite are not, and some ceramics such as clay pottery are not considered refractory. Refractories are distinguished from the ''refractory metals'', which are elemental metals and their alloys that have high melting temperatures. Refractories are defined by ASTM C71 as "non-metallic materials having those chemical and physical properties that make them applicable for structures, or as component ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary rock, sedimentary carbonate rock that contains a high percentage of the mineral Dolomite (mineral), dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). One of the first geologists to distinguish dolomite from limestone was Déodat Gratet de Dolomieu, a French mineralogist and geologist after whom it is named. He recognized and described the distinct characteristics of dolomite in the late 18th century, differentiating it from limestone. Most dolomite was formed as a magnesium replacement of limestone or of Lime (mineral), lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the v ...

Guadalupian
The Guadalupian is the second and middle Series (stratigraphy), series/Epoch (geology), epoch of the Permian. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains of New Mexico and Texas, and dates between 272.95 ± 0.5 – 259.1 ± 0.4 Mya. The series saw the rise of the therapsids, a minor extinction event called Olson's Extinction and a significant Extinction event, mass extinction called the end-Capitanian extinction event. The Guadalupian is also known as the Middle Permian. Name and background The Guadalupian is the second and middle series or epoch of the Permian. Previously called Middle Permian, the name of this epoch is part of a revision of Permian stratigraphy for standard global correlation. The name "Guadalupian" was first proposed in the early 1900s, and approved by the International Subcommission on Permian Stratigraphy in 1996. References to the Middle Permian still exist. The Guadalupian was p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hartlepool
Hartlepool ( ) is a seaside resort, seaside and port town in County Durham, England. It is governed by a unitary authority borough Borough of Hartlepool, named after the town. The borough is part of the devolved Tees Valley area with an estimated population of 92,600. The old town was founded in the 7th century, around the monastery of Hartlepool Abbey, on a headland. As the village grew into a town, in the Middle Ages, its harbour served as the County Palatine of Durham's official port. The new town of West Hartlepool was created, in 1835, after a new port was built and railway links from the South Durham coal fields (to the west) and from Stockton-on-Tees (to the south) were created. A parliamentary constituency covering both the old town and West Hartlepool was created, in 1867, called The Hartlepools (UK Parliament constituency), The Hartlepools. The two towns were formally merged into a single county borough, borough called Hartlepool, in 1967. Following the merger, the nam ...
