Crossgates Quarry
Crossgates Quarry is a disused limestone quarry in Crossgates, south of Scarborough, North Yorkshire, England. Fossils The limestone of Crossgates Quarry is of the Corallian Group. It was said in 1892 that "most of hespecies f Jurassic rockin former times marked Scarborough have either come from this or Ayton Quarries." Blake and Hudleston described the rock beds of the quarry as 2 feet of coral rag, 8 feet 1 inch of oolite Oolite or oölite (''egg stone'') is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the Ancient Greek word for egg (ᾠόν). Strictly, oolites consist of ooids of diameter 0.25–2 ... and corals, 2 feet of the coral shell-bed, and 13 feet 2 inches of oolites. In 1901, J. A. Hargreaves of the Yorkshire Naturalists' Union, commented that "Crossgates quarry lies immediately below the Coral Rag, and although fossils are numerous, it is almost impossible to extract them from the surr ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarborough, North Yorkshire
Scarborough () is a seaside town in the Borough of Scarborough in North Yorkshire, England. Scarborough is located on the North Sea coastline. Historic counties of England, Historically in the North Riding of Yorkshire, the town lies between 10 and 230 feet (3–70 m) above sea level, from the harbour rising steeply north and west towards limestone cliffs. The older part of the town lies around the harbour and is protected by a rocky headland. With a population of 61,749, Scarborough is the largest seaside resort, holiday resort on the Yorkshire Coast and largest seaside town in North Yorkshire. The town has fishing and service industries, including a growing digital and creative economy, as well as being a tourist destination. Residents of the town are known as Scarborians. History Origins The town was reportedly founded around 966 AD as by Thorgils Skarthi, a Viking raider, though there is no archaeological evidence to support these claims, made during the 1960s, as p ...

Corallian Group
The Corallian Group or Corallian Limestone is a geologic group in England. It is predominantly a coralliferous sedimentary rock, laid down in the Oxfordian stage of the Jurassic. It is a hard variety of " coral rag". Building stones from this geological structure tend to be irregular in shape. It is often found close to seams of Portland Limestone (e.g. Abbotsbury in Dorset, England). It is a younger limestone than its near-neighbour, the Oolitic, as found in the Cotswolds, in Gloucestershire. It is laterally equivalent to and interfingers with units of the Ancholme Group. A ridge of Corallian Limestone rises above the Vale of Avon and the Thames Valley in its Oxfordshire stretch. The Oxfordshire Corallian ridge is an escarpment holding back the hanging valley that is the Vale of White Horse and its hardness forced the River Thames to take a wide northern detour, to cut through the low ridge at Oxford. High points along the ridge are Cumnor Hurst and Wytham Hill. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ayton
Great Ayton is a village and civil parish in the Hambleton District of North Yorkshire, England. The River Leven (a tributary of the River Tees) flows through the village, which lies just north of the North York Moors. Etymology Great Ayton's name derives from Old English ''Ea-tun'', meaning 'river farm'. The river flowing through Great Ayton is the Leven, a tributary of the River Tees. A later addition of the word 'great' differentiates the village from nearby Little Ayton. History In the 18th and 19th centuries Great Ayton was a centre for the industries of weaving, tanning, brewing, and tile making. Subsequently, whinstone for road surfacing was also quarried from the Cleveland Dyke along with ironstone, jet and alum from the Cleveland Hills. Great Ayton was home to the Great Ayton Friends' School (Quaker) from 1841 until it closed in 1997. The village serves as the base for Cleveland Mountain Rescue Team.

Coral Rag
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oolite
Oolite or oölite (''egg stone'') is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the Ancient Greek word for egg (ᾠόν). Strictly, oolites consist of ooids of diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites. The term ''oolith'' can refer to oolite or individual ooids. Composition Ooids are most commonly composed of calcium carbonate ( calcite or aragonite), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. Dolomitic and chert ooids are most likely the result of the replacement of the original texture in limestone. Oolitic hematite occurs at Red Mountain near Birmingham, Alabama, along with oolitic limestone. They are usually formed in warm, supersaturated, shallow, highly agitated marine water intertidal environments, though some are formed in inland lakes. The mechanism of formation starts with a small fragment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yorkshire Naturalists' Union
The Yorkshire Naturalists' Union is an association of amateur and professional naturalists covering a wide range of aspects of natural history. It is one of United Kingdom's oldest extant wildlife organisations and oldest natural history federation. Its Mycological Committee, founded in 1892, is the oldest permanent organisation dedicated to the study of fungi in Great Britain. History The Yorkshire Naturalists' Union was founded in 1861 as the West Riding Consolidated Naturalists' Society. Initially a collaboration of five local natural history field clubs, additional clubs and societies from across Yorkshire continued to join. The association renamed itself the Yorkshire Naturalists' Union in 1876. Activities The Yorkshire Naturalists' Union organises joint field trips, co-operates with the British Association for the Advancement of Science and other county-sized associations, and publishes a journal, ''The Naturalist''.

Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, CaCO3 + heat → Calcium oxide, CaO + Carbon dioxide, CO2 This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere (unit), atmosphere), but a temperature around 1000 °C (1832 °F) (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. Early li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
