Seend Cleeve Quarry
Seend Cleeve Quarry () is a Geological Site of Special Scientific Interest at Seend Cleeve, Wiltshire, England, notified in 1987. It is important for its strata from the Oxfordian stage of the Jurassic period, containing fossil ammonites and bivalves which aid stratigraphy. The site was an iron ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the fo ... quarry between the middle of the 19th century and the 1960s, and in the 19th century Seend Iron Works was nearby. None of these facilities have been preserved; the site is now pasture.

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Seend Cleeve
Seend Cleeve is a large hamlet or sub-village immediately west of Seend in Wiltshire, England. It lies about southeast of the town of Melksham. A Primitive Methodist chapel with Sunday school was built in 1841 at Seend Cleeve. In 1849, the chapel was rebuilt in red brick with ashlar quoins. The chapel closed in 1979 and was converted into a private house in 2012. Seend Cleeve Quarry was a source of brown haematite; since 1987 the quarry has been a Geological Site of Special Scientific Interest. There was an ironworks in the second half of the 19th century, and quarrying continued until 1946. Seend Cleeve has two public houses: the ''Barge Inn'' on the Kennet and Avon Canal The Kennet and Avon Canal is a waterway in southern England with an overall length of , made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the cent ..., and the ''Brewery Inn''. References Further readi ...

Oxfordian (stage)
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 163.5 ± 1.0 Ma and 157.3 ± 1.0 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Oxford, Bedford, Peterborough, and in the cliffs at Scarborough, Red Cliff and Gristhorpe Bay. Rocks of this age are found also in Uig and Skye.

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonites
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

Bivalvia
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estim ... that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into Ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they a ...

Stratigraphy
Stratigraphy is a branch of geology concerned with the study of rock (geology), rock layers (Stratum, strata) and layering (stratification). It is primarily used in the study of sedimentary rock, sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith (geologist), William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of Stratum, strata or rock layering and the importance ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Metallic iron is virtually unknown on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seend Ironstone Quarry And Road Cutting
Seend Ironstone Quarry and Road Cutting () is a Geological Site of Special Scientific Interest at Seend in Wiltshire, England, notified in 1965. The site contains facies of Lower Greensand containing specimens of fauna not found elsewhere. Mining rights were leased just below the Bell Inn before 1856 where 10,000 tons of iron ore were mined. The quarried brown hematite ore was then smelted in blast furnaces from 1860 by Wlliam Sarl with three furnaces fifty feet high, and employing 300 men. Iron smelting continued intermittently until the mid 1870s, after which only quarrying was carried on. The ironworks were dismantled by 1890. The ironstone continued to be extracted and shipped for smelting elsewhere until after World War I. From around the 1920s the iron ore was calcined at the site for shipping and its iron oxide used in purification plants for town gas. The works appear to have continued functioning into the 1960s.

Victoria County History
The Victoria History of the Counties of England, commonly known as the Victoria County History or the VCH, is an English history project which began in 1899 with the aim of creating an encyclopaedic history of each of the historic counties of England, and was dedicated to Victoria of the United Kingdom, Queen Victoria. In 2012 the project was rededicated to Elizabeth II, Queen Elizabeth II in celebration of her Diamond Jubilee year. Since 1933 the project has been coordinated by the Institute of Historical Research in the University of London. History The history of the VCH falls into three main phases, defined by different funding regimes: an early phase, 1899–1914, when the project was conceived as a commercial enterprise, and progress was rapid; a second more desultory phase, 1914–1947, when relatively little progress was made; and the third phase beginning in 1947, when, under the auspices of the Institute of Historical Research, a high academic standard was set, and pr ...

Sites Of Special Scientific Interest In Wiltshire
__NOTOC__ The following is a list of Sites of Special Scientific Interest (SSSIs) in Wiltshire, England, United Kingdom. In England the body responsible for designating SSSIs is Natural England, which chooses a site because of its fauna, flora, geological or physiographical features. As of 2006, there are 134 sites designated in this Area of Search, of which the vast majority, 108, have been designated due to their biological interest, with just 21 due to their geological interest (and 5 for both). Natural England took over the role of designating and managing SSSIs from English Nature in October 2006 when it was formed from the amalgamation of English Nature, parts of the Countryside Agency and the Rural Development Service. Natural England, like its predecessor, uses the 1974–1996 county system and as such the same approach is followed here, rather than adopting the current local government or ceremonial county boundaries. The data in the table is taken from English Nature's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
