Petrifying Well
A petrifying well is a well or other body of water which gives objects a stone-like appearance. If an object is placed into such a well and left there for a period of months or years, the object acquires a stony exterior. Nature If an object is placed into such a well and left there for a period of weeks or months the object acquires a stony exterior. At one time this property was believed to be a result of magic or witchcraft, but it is an entirely natural phenomenon and due to a process of evaporation and deposition in waters with an unusually high mineral content. This process of petrifying is not to be confused with petrification wherein the constituent molecules of the original object are replaced (and not merely overlaid) with molecules of stone or mineral. Examples Notable examples of petrifying wells in England are the spring at Mother Shipton's Cave in Knaresborough and Matlock Bath, in Derbyshire. While in Ireland, such wells were noted by John Rutty on Howth Head,Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrified Teddy Bears (15011901552)
In geology, petrifaction or petrification () is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified (although harder, more durable matter such as bone, beaks, and shells survive the process better than softer remains such as muscle tissue, feathers, or skin). Petrifaction takes place through a combination of two similar processes: permineralization and replacement. These processes create replicas of the original specimen that are similar down to the microscopic level. Processes Permineralization One of the processes involved in petrifaction is permineralization. The fossils created through this process tend to contain a large amount of the original material of the specimen. This process occurs when groundwater containing dissolved minerals (most commonly q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matlock Bath
Matlock Bath is a village and civil parish in Derbyshire, England. It lies in the Peak District, south of Matlock on the main A6 road, and approximately halfway between Buxton and Derby. The population of the civil parish at the 2011 census was 753. Originally built at the head of a dead-end dirt road running along the valley of the River Derwent from Matlock, the settlement developed in the 19th century as residential and a spa town which remains a tourist destination. The steep hillside restricts development with most buildings on one side of the valley and only footbridges across the river. The road was upgraded, becoming a through-way, now designated A6, avoiding the previous coaching road approach to Matlock from Cromford over very steep hills near to the Riber plateau area. Matlock Dale is a hamlet about north of the village, and the term also refers to this stretch of the river valley. History In 1698, warm springs were discovered and a bath house was built.

Water Wells
A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets or large water bags that are raised mechanically or by hand. Water can also be Aquifer storage and recovery, injected back into the aquifer through the well. Wells were first constructed at least eight thousand years ago and historically vary in construction from a simple scoop in the sediment of a dry watercourse to the qanats of Iran, and the stepwells and Sakia, sakiehs of India. Placing a lining in the well shaft helps create stability, and linings of wood or wickerwork date back at least as far as the Iron Age. Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech a ...

Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carbonate ...

Stalactite
A stalactite (, ; from the Greek 'stalaktos' ('dripping') via ''stalassein'' ('to drip') is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite. Stalactites may be composed of lava, minerals, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). A stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves. The corresponding formation on the floor of the cave is known as a stalagmite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground". Another example is that ''stalactites'' "hang on ''T''ight" and ''stalagmites'' "''M''ight grow up" †... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleothem
A speleothem (; ) is a geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark brown. Speleothems can also be brown d ...

Howth Head
Howth Head ( ; ''Ceann Bhinn Éadair'' in Irish) is a peninsula northeast of the city of Dublin in Ireland, within the governance of Fingal County Council. Entry to the headland is at Sutton while the village of Howth and the harbour are on the north-eastern face. Most of Howth Head is occupied by the Hill of Howth, though there are other regions, such as the tombolo at Sutton, extensive beaches on the northern shores, and small ones in other parts. The Baily Lighthouse is on the southeastern part of Howth Head. Nearby are the districts of Baldoyle and Portmarnock, and adjacent is the nature reserve of North Bull Island. History The earliest mention of the peninsula may be on a map attributed to Claudius Ptolemy, where it was called ''Edri Deserta'' or in Greek (''Edrou Heremos'', Edar's isolated place). Here it was portrayed as an island, but it is not clear if this was due to actual separation from the headland or inaccurate information available to the cartographer. Other ...

John Rutty
John Rutty (1697–1775) was a Dublin Quaker physician and naturalist born in Melksham, Wiltshire, England. He was the author of many texts including ''A methodical synopsis of the Mineral Waters of Ireland'' (1757) and ''An Essay towards the Natural History of the County of Dublin'' (1772). After his death his spiritual diary was published, and the botanist William Henry Harvey named the genus Acanthaceae '' Ruttya'' after him. Life He was born of Quaker parents on 25 December 1698. After a medical education at the University of Leyden, where he graduated M.D. in 1723 and read a thesis ''De Diarrhœa'', he settled in Dublin as a physician in 1724. There he practised throughout his life. He lived simply and often gave his services to the poor. On 6 April 1775, John Wesley records that he 'visited that venerable man Dr. Rutty.' Rutty then lived in rented rooms at the eastern corner of Boot Lane and Mary's Lane in Dublin. He died on 27 April 1775, and was buried in a Quaker buri ...

Derbyshire
Derbyshire ( ) is a ceremonial county in the East Midlands, England. It includes much of the Peak District National Park, the southern end of the Pennine range of hills and part of the National Forest. It borders Greater Manchester to the north-west, West Yorkshire to the north, South Yorkshire to the north-east, Nottinghamshire to the east, Leicestershire to the south-east, Staffordshire to the west and south-west and Cheshire to the west. Kinder Scout, at , is the highest point and Trent Meadows, where the River Trent leaves Derbyshire, the lowest at . The north–south River Derwent is the longest river at . In 2003, the Ordnance Survey named Church Flatts Farm at Coton in the Elms, near Swadlincote, as Britain's furthest point from the sea. Derby is a unitary authority area, but remains part of the ceremonial county. The county was a lot larger than its present coverage, it once extended to the boundaries of the City of Sheffield district in South Yorkshire where it cov ...

Knaresborough
Knaresborough ( ) is a market and spa town and civil parish in the Borough of Harrogate, in North Yorkshire, England, on the River Nidd. It is east of Harrogate. History Knaresborough is mentioned in the Domesday Book of 1086 as ''Chenaresburg'', meaning "Cenheard's fortress", in the wapentake of Burghshire, renamed Claro Wapentake in the 12th century. Knaresborough Castle is Norman; around 1100, the town began to grow. It provided a market and attracted traders to service the castle. The parish church, St John's, was established around this time. The earliest identified Lord of Knaresborough is around 1115 when Serlo de Burgh held the Honour of Knaresborough from the King. Hugh de Morville was granted the Honour of Knaresborough in 1158. He was constable of Knaresborough and leader of the group of four knights who murdered Archbishop Thomas Becket at Canterbury Cathedral on 29 December 1170. The four knights fled to Knaresborough and hid at the castle. Hugh de Morvil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mother Shipton's Cave
Mother Shipton's Cave (or "Old Mother Shipton's Cave") is at Knaresborough, North Yorkshire, England, near the River Nidd. Nearby is a petrifying well, also known as a dropping well. The latter is the oldest tourist attraction to charge a fee in England, and has been operated since 1630. The water of the well is so rich in sulphate and carbonate that artefacts may be put in the well to be "petrified" (encrusted) as a tourist attraction. The place is associated with the legendary soothsayer and prophetess Mother Shipton (), born Ursula Southeil, and reportedly the wife of Toby Shipton. According to legend A legend is a genre of folklore that consists of a narrative featuring human actions, believed or perceived, both by teller and listeners, to have taken place in human history. Narratives in this genre may demonstrate human values, and possess ..., she was born in the cave. The cave and dropping well, together with other attractions, remain open to visitors and are run p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
