Babingtonite
Babingtonite is a calcium iron manganese inosilicate mineral with the formula Ca2( Fe, Mn)Fe Si5 O14(O H). It is unusual in that iron(III) completely replaces the aluminium so typical of silicate minerals. It is a very dark green to black translucent (in thin crystals or splinters) mineral crystallizing in the triclinic system with typically radial short prismatic clusters and druzy coatings. It occurs with zeolite minerals in cavities in volcanic rocks. Babingtonite contains both iron(II) and iron(III) and shows weak magnetism. It has a Mohs hardness of 5.5 to 6 and a specific gravity of 3.3. It was first described in 1824 from samples from Arendal, Aust-Agder, Norway (which is its type locality) and was named after the Irish physician and mineralogist William Babington (1757–1833). It is the official mineral (mineral emblem) of the Commonwealth of Massachusetts. The first published report of babingtonite in Massachusetts was by Francis Alger in 1844, who credited Thomas Nu ...

William Babington (physician)
William Babington Royal Society#Fellows, FRS Geological Society of London, FGS (21 May 1756 – 29 April 1833) was an Anglo-Irish people, Anglo-Irish physician and Mineralogy, mineralogist. Life and work William Babington was born in Portglenone, near Coleraine, Antrim, Ireland. He was the son of Rev. Humphrey Babington family, Babington, the great-great-grandson of Brutus Babington (sent to Ireland by James VI and I), and his wife Anne (née Buttle). Apprenticed to a practitioner at Londonderry, and afterwards completed his medical education at Guy's Hospital, London, but without at that time taking a medical degree. In 1777 he was made assistant surgeon to Haslar (Naval) Hospital, and held this appointment for four years. He then obtained the position of apothecary to Guy's Hospital, and also lectured on chemistry in the medical school. He resigned the post of apothecary, and, having obtained the necessary degree of MD from the University of Aberdeen in 1795. in 1796 he joine ...

Inosilicate
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. In mineralogy, silica (silicon dioxide, ) is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphism (materials science), polymorphs. On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working the crust for billions of years. These processes include partial melting, crystallization, fractionation, metamorphism, weathering, and diagenesis. Living organisms also contribute to this carbonate–silicate cycle, geologic cycle. For example, a type of plankton known as diatoms construct their exoskeletons ("frustules") from silica extracted from seawater. The frustules of dead diatoms are a major constituent of deep ocean sediment, and of diatomaceous e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yunnan Province
Yunnan , () is a landlocked province in the southwest of the People's Republic of China. The province spans approximately and has a population of 48.3 million (as of 2018). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi, and Tibet Autonomous Region, Tibet as well as Southeast Asian countries: Vietnam, Laos, and Myanmar. Yunnan is China's fourth least developed province based on disposable income per capita in 2014. Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys by as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China.

Qiaojia County
Qiaojia County () is a county in the northeast of Yunnan province, China, bordering Sichuan province to the north and west. The population was 625,000 in 2019, 33,200 of whom belonged to ethnic minorities. It is both the southernmost and westernmost county-level division of Zhaotong City and located entirely on the right bank of the Jinsha River. The river valleys of Qiaojia are some of the lowest points in Yunnan province, at around 900 meters. The name of the county literally means 'City of industrious artisans'.

Prehnite
Prehnite is an inosilicate of calcium and aluminium with the formula: Ca2Al(AlSi3O10)(OH)2. Limited Fe3+ substitutes for aluminium in the structure. Prehnite crystallizes in the orthorhombic crystal system, and most often forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Very rarely will it form distinct, well-individualized crystals showing a square-like cross-section, including those found at the Jeffrey Mine in Asbestos, Quebec, Canada. Prehnite is brittle with an uneven fracture and a vitreous to pearly luster. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue, pink or white. In April 2000, rare orange prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent, and rarely transparent. Though not a zeolite, prehnite is found associated with minerals suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Rams ...

Mineralogist
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. History Early writing on mineralogy, especially on gemstones, comes from ancient Babylonia, the ancient Greco-Roman world, ancient and medieval China, and Sanskrit texts from ancient India and the ancient Islamic world. Books on the subject included the ''Naturalis Historia'' of Pliny the Elder, which not only described many different minerals but also explained many of their properties, and Kitab al Jawahir (Book of Precious Stones) by Persian scientist Al-Biruni. The German Renaissance specialist Georgius Agricola wrote works such as '' De re metallica'' (''On Metals'', 1556) and ''De Natura Fossilium'' (''O ...

Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
