Coral Rag
Coral rag is a rubbly limestone composed of ancient coral reef material. The term also refers to the building blocks quarried from these strata, which are an important local building material in areas such as the coast of East Africa and the southeastern United States littoral (e.g. Florida, Bermuda). It is also the name of a member—the Coral Rag Member—of the Upper Oxfordian Coralline Oolite Formation of North Yorkshire. "Calne Freestone And Coral Rag" is a former name for the Stanford Formation, which stretches from Westbury in Wiltshire to Waddesdon in Buckinghamshire.

Bridgetown Barbados Parliament Building
Bridgetown (UN/LOCODE: BB BGI) is the capital and largest city of Barbados. Formerly The Town of Saint Michael, the Greater Bridgetown area is located within the parish of Saint Michael. Bridgetown is sometimes locally referred to as "The City", but the most common reference is simply "Town". As of 2014, its metropolitan population stands at roughly 110,000. The ''Bridgetown'' port, found along Carlisle Bay (at ) lies on the southwestern coast of the island. Parts of the Greater Bridgetown area (as roughly defined by the Ring Road Bypass or more commonly known as the ABC Highway), sit close to the borders of the neighbouring parishes Christ Church and St. James. The Grantley Adams International Airport for Barbados, is located southeast of Bridgetown city centre. It is the largest and only airport on the island. It has daily flights to major cities in the United Kingdom, United States, Canada and the Caribbean. There is no longer a local municipal government, but it is a c ...

Coral Sand
Coral sand is a form of aragonite sand particles originating in tropical and sub-tropical marine environments primarily from bioerosion of limestone skeletal material of marine organisms. Often, this is due to corallivores, such as parrotfish, which excrete sand after digestion. However, the term "coral" in ''coral sand'' is used loosely in this sense to mean limestone of recent biological origin; corals are not the dominant contributors of sand particles to most such deposits. Rather, coral sand is a mix of coral and/or remnant skeletal fragments of foraminifera, calcareous algae, molluscs, and crustaceans . Because it is composed of limestone, coral sand is acid-soluble. Environmental issues Coral sand mining is a significant industry in some areas, and can have damaging environmental effects. Over 500,000 tons of coral sand were mined annually from Mauritius until being banned in October 2001. Many Comoros beaches have been scarred by sand mining. Over 250 tons of shells ...

Keystone (limestone)
Keystone is a type of limestone, or coral rag, quarried in the Florida Keys, in particular from Windley Key fossil quarry, which is now a State Park of Florida. The limestone is Pleistocene in age, and the rock primarily consists of scleractinian coral, such as Elkhorn coral and Brain coral. The Hurricane Monument, commemorating victims of the Labor Day Hurricane of 1935, and located at mile marker 82 on U.S. Route 1 near Islamorada, is constructed of keystone, as is the David W. Dyer Federal Building and United States Courthouse. See also *List of types of limestone This article lists types of limestone arranged according to generic type and location.

Corallian Limestone
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. The outcrop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
