Bagshot Beds
In geology, the Bagshot Beds are a series of sands and clays of shallow-water origin, some being fresh-water, some marine. They belong to the upper Eocene formation of the London and Hampshire basins, in England and derive their name from Bagshot Heath in Surrey. They are also well developed in Hampshire, Berkshire and the Isle of Wight. The following divisions are generally accepted: *Upper Bagshot Beds — Barton sand and Barton clay. *Middle Bagshot Beds — Bracklesham Beds. *Lower Bagshot Beds — Bournemouth Beds and Alum Bay Beds. The lower division consists of pale-yellow, current-bedded sand and loam, with layers of pipeclay and occasional beds of flint pebbles. In the London basin, wherever the junction of the Bagshot beds with the London clay is exposed, it is clear that no sharp line can be drawn between these formations. The Lower Bagshot Beds may be observed at Brentwood, Billericay and High Beach in Essex; outliers, capping hills of London clay, occur at Hamp ...

Ypresian
In the geologic timescale the Ypresian is the oldest age or lowest stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the lower Eocene. Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. Stratigraphic definition The Ypresian Stage was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones. The Ypresian shares its name with the Belgian Ieper Grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bagshot, Surrey
Bagshot is a town in the Surrey Heath borough of Surrey, England, approximately southwest of central London. In the past, Bagshot served as an important staging post between London, Southampton and the West Country, evidenced by the original coaching inns still present in the town today. Much of the land surrounding Bagshot is owned by the Ministry of Defence. The village is adjacent to junction 3 of the M3 motorway.

Essex
Essex () is a county in the East of England. One of the home counties, it borders Suffolk and Cambridgeshire to the north, the North Sea to the east, Hertfordshire to the west, Kent across the estuary of the River Thames to the south, and Greater London to the south and south-west. There are three cities in Essex: Southend, Colchester and Chelmsford, in order of population. For the purposes of government statistics, Essex is placed in the East of England region. There are four definitions of the extent of Essex, the widest being the ancient county. Next, the largest is the former postal county, followed by the ceremonial county, with the smallest being the administrative county—the area administered by the County Council, which excludes the two unitary authorities of Thurrock and Southend-on-Sea. The ceremonial county occupies the eastern part of what was, during the Early Middle Ages, the Anglo-Saxon Kingdom of Essex. As well as rural areas and urban areas, it forms part of ...

Billericay
Billericay ( ) is a town and civil parish in the Borough of Basildon, Essex, England. It lies within the London Basin and constitutes a commuter town east of Central London. The town has three secondary schools and a variety of open spaces. It is thought to have been occupied since the Bronze Age. Toponym The origin of the name Billericay is unclear. It was first recorded as "Byllyrica" in 1291. The urban settlement, which was within the manor and parish of Great Burstead, was one of many founded in the late 13th century in an already densely populated rural landscape. Several suggestions for the origin of the place name include: * ''Villa Erica'' (Heather Villa), suggesting a Romano-British origin. * ''bellerīca'', a medieval Latin word meaning 'dyehouse or tanhouse'. * ''billers'', a traditional name for watercress, for which Bilbrook in Somerset and Staffordshire are named. Watercress was farmed in Billericay springs during the 20th century. Although the precise etymolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brentwood, Essex
Brentwood is a town in the Borough of Brentwood, in the county of Essex in the East of England. It is in the London commuter belt, situated 20 miles (30 km) east-north-east of Charing Cross and close by the M25 motorway. In 2017, the population of the town was estimated to be 54,885.

However, '' brent'' was the middle English for "burnt". The name describes the presumed re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along streams and be ...

Catlinite
Catlinite, also called pipestone, is a type of argillite (metamorphosed mudstone), usually brownish-red in color, which occurs in a matrix of Sioux Quartzite. Because it is fine-grained and easily worked, it is prized by Native Americans, primarily those of the Plains nations, for use in making ceremonial pipes, known as chanunpas or čhaŋnúŋpas in the Lakota language. Pipestone quarries are located and preserved in Pipestone National Monument outside Pipestone, Minnesota, in Pipestone County, Minnesota, and at the Pipestone River in Ontario, Canada. Name The term ''Catlinite'' came into use after the American painter George Catlin visited the quarries in Minnesota in 1835; but it was Philander Prescott who first wrote about the rock in 1832, noting that evidence indicated that American Indians had been using the quarries since at least as far back as 1637. Catlinite Properties and Quarries Minnesota catlinite is buttery smooth and can be cut with a regular hacksaw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand ( particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Alum Bay Beds
An alum () is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula , where is a monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula . Other alums are named after the monovalent ion, such as sodium alum and ammonium alum. The name "alum" is also used, more generally, for salts with the same formula and structure, except that aluminium is replaced by another trivalent metal ion like chromium, and/or sulfur is replaced by another chalcogen like selenium. The most common of these analogs is chrome alum . In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, , which is used for most industrial flocculation (the variable is an integer whose size depends on the amount of water absorbed into the alum). In medicine, "alum" may also refer to aluminium hydroxide gel used as a vaccine adjuvant. History Alum found at archaeolo ...

Bournemouth Beds
Bournemouth () is a coastal resort town in the Bournemouth, Christchurch and Poole council area of Dorset, England. At the 2011 census, the town had a population of 183,491, making it the largest town in Dorset. It is situated on the English south coast, equidistant () from Dorchester and Southampton. Bournemouth is part of the South East Dorset conurbation, which has a population of 465,000. Before it was founded in 1810 by Lewis Tregonwell, the area was a deserted heathland occasionally visited by fishermen and smugglers. Initially marketed as a health resort, the town received a boost when it appeared in Augustus Granville's 1841 book, ''The Spas of England''. Bournemouth's growth accelerated with the arrival of the railway, and it became a town in 1870. Part of the historic county of Hampshire, Bournemouth joined Dorset for administrative purposes following the reorganisation of local government in 1974. Through local government changes in 1997, the town began to be ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barton Beds
Barton Beds (now the Barton Group) is the name given to a series of grey and brown clays, with layers of sand, of Upper Eocene age (around 40 million years old), which are found in the Hampshire Basin of southern England. They are particularly well exposed in the cliffs at Barton-on-Sea, which is the type locality for the Barton Beds, and lends its name to the Bartonian age of the Eocene epoch. The clay is abundant in fossils, especially molluscs. The beds are found in the Hampshire Basin, and are well exposed in the cliffs of Barton, Hordle, and on the Isle of Wight.Archibald Geikie, (1903), ''Text-book of Geology, Volume 2'', page 1233. The cliffs at Barton are the world type locality for the Barton Beds.Janet M. Hooke, (1998), ''Coastal Defence and Earth Science Conservation'', pages 246-7. Geological Society. The beds consist of grey, greenish and brown clays with bands of sand and have long been well known for the abundance and excellent preservation of their fossils. More ...
