Denehole
A denehole (alternatively dene hole or dene-hole) is an underground structure consisting of a number of small chalk caves entered by a vertical shaft. The name is given to certain caves or excavations in England, which have been popularly supposed to have been created by the Danes or some other of the early northern invaders of the country. The common spelling Dane hole is adduced as evidence of this, and individual names, such as Vortigern's Caves at Margate, and Canute's Gold Mine near Bexley, naturally follow the same theory. The word, however, is probably derived from the Anglo Saxon ''den'', a hole or valley. The lack of evidence found in them has led to long arguments as to their function. Form The general outline of the formation of these caves is invariably the same. The entrance is a vertical shaft some 3 feet (1 m) in diameter falling, on an average, to a depth of 60 feet (20 m). The depth is regulated by the depth of the chalk layer from the surface, although chalk ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hangman's Wood
Hangman's Wood and Deneholes is a biological Site of Special Scientific Interest in Little Thurrock in Essex. The deneholes, which were created by medieval chalk mining, are a Scheduled Monument. The name Hangmans Wood dates back to at least the mid-17th century, when it was recorded on an estate map. Trees in the wood include oak, ash, sycamore and wild cherry. left, Investigating a denehole in Hangman's WoodThe wood contains a number of deneholes which were investigated by the Essex Field Club at the end of the 19th century.Tony Benton, ''Boldly from the Marshes'' There is normally no access to the deneholes, but permission can be obtained from the council. The deneholes are the most important underground hibernation sites for bats in Essex, with three species; brown long-eared bat, Natterer's bat and Daubenton's bat. The oak woodland is ancient, and it provides a feeding habitat for the bats. The deneholes in the wood, which were sometimes known as Cunobeline's gold mi ...

Flaxman Charles John Spurrell
Flaxman Charles John Spurrell (8 September 1842 – 25 February 1915) was a British archaeologist, geologist and photographer who worked mainly in Kent and East Anglia. He was also a noted egyptologist, working closely with Flinders Petrie. Family and early life Born at Mile End in Stepney, London, Spurrell was the eldest son of Dr. Flaxman and Ann Spurrell and a descendant of the Spurrell family of Norfolk. He was a nephew of the Rev. Frederick Spurrell, a fellow archaeologist, and an uncle of the biologist and author Herbert George Flaxman Spurrell. Not long after his birth, the family settled at Bexley in Kent, living for many years at The Priory, Picardy Road, Belvedere (later home to the Priory Conservative Club). Spurrell was educated at Epsom College and went on to study medicine, although he never completed his studies.Becky Shaw and Andrew Shaw, ''The Quiet Man of Kent: The Contribution of F. C. J.

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells ...

Vortigern
Vortigern (; owl, Guorthigirn, ; cy, Gwrtheyrn; ang, Wyrtgeorn; Old Breton: ''Gurdiern'', ''Gurthiern''; gle, Foirtchern; la, Vortigernus, , , etc.), also spelled Vortiger, Vortigan, Voertigern and Vortigen, was a 5th-century warlord in Britain, known perhaps as a king of the Britons or at least connoted as such in the writings of Bede and Gildas. His existence is contested by scholars and information about him is obscure. He may have been the "superbus tyrannus" said to have invited Hengist and Horsa to aid him in fighting the Picts and the Scots, whereupon they revolted, killing his son in the process and forming the Kingdom of Kent. It is said that he took refuge in North Wales, and that his grave was in Dyfed or the Llŷn Peninsula. Gildas later denigrated Vortigern for his misjudgement and also blamed him for the loss of Britain. He is cited at the beginning of the genealogy of the early Kings of Powys.

Chrétien De Troyes
Chrétien de Troyes (Modern ; fro, Crestien de Troies ; 1160–1191) was a French poet and trouvère known for his writing on Arthurian subjects, and for first writing of Lancelot, Percival and the Holy Grail. Chrétien's works, including '' Erec and Enide'', ''Lancelot'', '' Perceval'' and '' Yvain'', represent some of the best-regarded of medieval literature. His use of structure, particularly in ''Yvain'', has been seen as a step towards the modern novel. Life Little is known of his life, but he seems to have been from Troyes or at least intimately connected with it. Between 1160 and 1172 he served (perhaps as herald-at-arms, as Gaston Paris speculated) at the court of his patroness Marie of France, Countess of Champagne, daughter of King Louis VII and Eleanor of Aquitaine, who married Count Henry I of Champagne in 1164. Later, he served the court of Philippe d'Alsace, Count of Flanders. Works Chrétien's works include five major poems in rhyming eight-syllable ...

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 ...

Agricultural Lime
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate. Additional chemicals vary depending on the mineral source and may include calcium oxide. Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling. All of these types of lime are sometimes used as soil conditioners, with a common theme of providing a base to correct acidity, but lime for farm fields today is often crushed limestone. Historically, liming of farm fields in centuries past was often done with burnt lime; the difference is at least partially explained by the fact that affordable mass-production-scale fine milling of stone and ore relies on technologies developed since the mid-19th century. Some effects of agricultural lime on soil are: * it increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea wit ...

Information Sign About The Dene Hole In Capstone Park - Geograph
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation. Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at the next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information relevant ...

Barking Creek
Barking Creek joins the River Roding to the River Thames. It is fully tidal up to the Barking Barrage (a weir), which impounds a minimum water level through Barking. In the 1850s, the creek was home to England's largest fishing fleet and a Victorian icehouse – where the fish were landed and stored prior to being transferred to London's fish markets. Barking Creek contains a small number of house boats, and the former village of Creekmouth is nearby. The Barking Creek Barrier, a tidal flood barrier, was constructed in the 1980s as part of the Thames flood defence system, opening in 1983. Like all of the subsidiary gates, it is normally closed before, and opened after, the main Thames Barrier. The barrier is 38 metres wide, held aloft by two 40 metre towers to allow boats to pass at high tide. See also * Battle of Barking Creek, a 'friendly fire' incident at the start of WW2 * RAF Hornchurch Royal Air Force Hornchurch or RAF Hornchurch is a former Royal Air Force Royal Ai ...
