Heathstone
Carrstone (or carstone, also known as Silsoe, heathstone, ironstone or gingerbread) is a sedimentary sandstone conglomerate formed during the Cretaceous period. It varies in colour from light to dark rusty ginger. Used as a building stone it can be found in Bedfordshire, Cambridgeshire and extensively in the historic buildings of northwest Norfolk. Carrstone can vary in quality depending on factors such as the degree of iron oxide present, and sufficient pressure to form the matrix. Carrstone can also phase into puddingstone, ferricrete and silver carr. Because of its variations it does not lend itself to carving or finer work. Carrstonework can be seen in forms such as: random carrstone, coursed carrstone, ashlared carrstone, all with, or without, galleting. Other patterns of use are: rough carrstone sipps (slips, shale or brickettes) and cut carrstone sipps, both used in masonry fields between brickwork quoins. Cut carrstone sipps or shales are used extensively at Sandringham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silver Carrstone 1
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burgh Castle
Burgh Castle is a village and civil parish in the English county of Norfolk. Burgh Castle is located south-west of Great Yarmouth and east of Norwich. The parish was part of Suffolk until 1974. History Burgh Castle was likely the site of a Neolithic settlement due to an abundance of flint and bronze axe-heads being discovered in the area. Burgh Castle is the location of a Roman fortification called ''Gariannonum'' which dates to the third century; the fort was part of system of coastal defence, the Saxon Shore, against Anglo-Saxon incursions on the East Anglian coast. The site is managed by the Norfolk Archaeological Trust and is open free of charge to the public. Bradwell's name is of mixed Anglo-Saxon and Norman origin and derives from the Old English ''burh'' (meaning fort) and the Norman French 'castle.' It has been suggested by the Elizabethan historian William Camden, that Burgh Castle is the site of Cnobheresburg, the first Irish monastery in southern England ...

Flitcham, Norfolk
Flitcham is a village and civil parish in the English county of Norfolk. The village is located north-east of King's Lynn and north-west of Norwich, along the River Babingley. Together with the villages of West Newton, Shernborne and Anmer, Flitcham forms part of the Royal Sandringham Estate. History Flitcham's name is of Anglo-Saxon origin and derives from the Old English for a village or settlement where 'flitches' of bacon were cured. There is, however, an alternate local theory that Flitcham's name derives from ''Felix-ham'' as the site of Saint Felix's original monastery after he arrived in East Anglia in the Seventh Century. In 1948, the site of a Roman villa was excavated close to Denbeck Wood, within the parish. After excavation, the villa was found to have glazed windows, a tessellated floor and a small courtyard flanked by other buildings from the same period. Further artefacts, including coins, pottery and metalwork dating from the Third and Forth Centuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concretion
A concretion is a hard and compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word ''concretion'' is borrowed from Latin , itself derived from ''concrescere'' , from ''con-'' and ''crescere'' . Concretions form within layers of sedimentary strata that have already been deposited. They usually form early in the burial history of the sediment, before the rest of the sediment is hardened into rock. This concretionary cement often makes the concretion harder and more resistant to weathering than the host stratum. There is an important distinction to draw between concretions and nodules. Concretions are formed from mineral precipitation around some kind of nucleus while a nodule is a replacement body. Descriptions dating from the 18th century attest to the fact that concretions have long been regarde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glauconite
Glauconite is an iron potassium phyllosilicate ( mica group) mineral of characteristic green color which is very friable and has very low weathering resistance. It crystallizes with a monoclinic geometry. Its name is derived from the Greek () meaning 'bluish green', referring to the common blue-green color of the mineral; its sheen ( mica glimmer) and blue-green color. Its color ranges from olive green, black green to bluish green, and yellowish on exposed surfaces due to oxidation. In the Mohs scale it has a hardness of 2, roughly the same as gypsum. The relative specific gravity range is 2.4–2.95. It is normally found as dark green rounded concretions with the dimensions of a sand grain. It can be confused with chlorite (also of green color) or with a clay mineral. Glauconite has the chemical formula . Glauconite particles are one of the main components of greensand, glauconitic siltstone and glauconitic sandstone. Glauconite has been called a marl in an old and br ...

Feldspar
Feldspar ( ; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust and 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Etymology The name ''feldspar'' derives from the German , a compound of the words ' ("field") and ("flake"). had long been used as the word for "a rock easily cleaved into flakes"; was introduced in the 18th century as a more specific term, referring perhaps to its comm ...
