Rowley Rag
Rowley Rag was a volcanic dolerite stone quarried in the stone quarries (known locally as the 'Quacks') of the Rowley Hills in the West Midlands of the United Kingdom, straddling the border of Rowley Regis and Dudley. The main quarry was on Turner's Hill, and in the 1960s was, in fact, two separate quarries, the Edwin Richards and Hailstone quarries, with a road between them leading to the top of the hill. At that time, hexagonal pillars similar to those of the Giant's Causeway in Ireland could be seen on one of the quarry faces. The Edwin Richards quarry was combined with the Hailstone quarry by removing the disused road between them. It remained active until 2008, operated by Midland Quarry Products. During the 1980s and 1990s, The Rowley dolerite is an intrusion of late Carboniferous age in the form of a lopolith. The country rock consists of the Etruria Marl Formation. The main use of the Rowley Rag stone was in the production of road surfaces and kerbstones. A public house ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Public House
A pub (short for public house) is a kind of drinking establishment which is licensed to serve alcoholic drinks for consumption on the premises. The term ''public house'' first appeared in the United Kingdom in late 17th century, and was used to differentiate private houses from those which were, quite literally, open to the public as "alehouses", "taverns" and "inns". By Georgian times, the term had become common parlance, although taverns, as a distinct establishment, had largely ceased to exist by the beginning of the 19th century. Today, there is no strict definition, but CAMRA states a pub has four characteristics:GLA Economics, Closing time: London's public houses, 2017 # is open to the public without membership or residency # serves draught beer or cider without requiring food be consumed # has at least one indoor area not laid out for meals # allows drinks to be bought at a bar (i.e., not only table service) The history of pubs can be traced to Roman taverns in B ...

Quarrying In The United Kingdom
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 operations was ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igneous Rocks
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by King Charles II as The Royal Society and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow of the ...

Lunar Society
The Lunar Society of Birmingham was a British dinner club and informal learned society of prominent figures in the Midlands Enlightenment, including industrialists, natural philosophers and intellectuals, who met regularly between 1765 and 1813 in Birmingham. At first called the Lunar Circle, "Lunar Society" became the formal name by 1775. The name arose because the society would meet during the full moon, as the extra light made the journey home easier and safer in the absence of street lighting. The members cheerfully referred to themselves as ''"lunaticks"'', a pun on lunatics. Venues included Erasmus Darwin's home in Lichfield, Matthew Boulton's home, Soho House, Bowbridge House in Derbyshire, and Great Barr Hall. Membership and status The Lunar Society evolved through various degrees of organisation over a period of up to fifty years, but was only ever an informal group. No constitution, minutes, publications or membership lists survive from any period, and evidence of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Withering
William Withering FRS (17 March 1741 – 6 October 1799) was an English botanist, geologist, chemist, physician and first systematic investigator of the bioactivity of digitalis. Withering was born in Wellington, Shropshire, the son of a surgeon. He trained as a physician and studied medicine at the University of Edinburgh Medical School. He worked at Birmingham General Hospital from 1779. The story is that he noticed a person with dropsy (swelling from congestive heart failure) improve remarkably after taking a traditional herbal remedy; Withering became famous for recognising that the active ingredient in the mixture came from the foxglove plant. The active ingredient is now known as digoxin, after the plant's scientific name. In 1785, Withering published ''An Account of the Foxglove and some of its Medical Uses'', which contained reports on clinical trials and notes on digitalis's effects and toxicity. Biography Born in England, Withering attended Edinburgh Medical School ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Country
The Black Country is an area of the West Midlands county, England covering most of the Metropolitan Boroughs of Dudley, Sandwell and Walsall. Dudley and Tipton are generally considered to be the centre. It became industrialised during its role as one of the birth places of the Industrial Revolution across the English Midlands with coal mines, coking, iron foundries, glass factories, brickworks and steel mills, producing a high level of air pollution. The name dates from the 1840s, and is believed to come from the soot that the heavy industries covered the area in, although the 30-foot-thick coal seam close to the surface is another possible origin. The road between Wolverhampton and Birmingham was described as "one continuous town" in 1785. Extent The Black Country has no single set of defined boundaries. Some traditionalists define it as "the area where the coal seam comes to the surface – so West Bromwich, Coseley, Oldbury, Blackheath, Cradley Heath, Old Hill, B ...

Country Rock (geology)
In geology, country rock is the rock native to an area, in contrast to any intrusion of viscous geologic material, commonly magma, or perhaps rock salt (in salt domes) or unconsolidated sediments. Magma is typically less dense than the rock it intrudes, widening and filling existing cracks, sometimes melting the already-existing country rock. The term "country rock" is similar to, and in many cases interchangeable with, the terms basement and wall rocks. Country rock can denote the widespread lithology of a region in relation to the rock which is being discussed or observed. Geologic settings Settings in geology when the term ''country rock'' is used include: Igneous intrusions When describing a pluton or dike, the igneous rock can be described as intruding the surrounding ''country rock'', the rock into which the pluton has intruded.Newfoundland and LabradorGlossary of Geological Terms Accessed June 2018.

Lopolith
A lopolith is a large igneous intrusion which is lenticular in shape with a depressed central region. Lopoliths are generally concordant with the intruded strata with dike or funnel-shaped feeder bodies below the body. The term was first defined and used by Frank Fitch Grout during the early 1900s in describing the Duluth gabbro complex in northern Minnesota and adjacent Ontario. Lopoliths typically consist of large layered intrusions that range in age from Archean to Eocene. Examples include the Duluth gabbro, the Sudbury igneous complex of Ontario, the Bushveld igneous complex of South Africa, the Great Dyke in Zimbabwe, the Skaergaard complex of Greenland and the Humboldt lopolith of Nevada. The Sudbury occurrence has been attributed to an impact event and associated crustal melting.
