Susannite
Susannite is a lead sulfate carbonate hydroxide mineral. It has the formula Pb4SO4(CO3)2(OH)2. Susannite is the higher temperature phase of the two and forms above 80 °C when fluids oxidize the lead ore deposits. It is Polymorphism (materials science), trimorphous with leadhillite and macphersonite. Susannite crystallizes in the trigonal system. It is quite soft with a Mohs hardness of 2.5 to 3.0 and a relatively high specific gravity of 6.57. It was discovered in 1827 in the Susannah Mine, Leadhills in the county of Lanark, Scotland. In addition to the type locality (geology), type locality in Scotland, it has also been reported from various locations in Germany, the Tiger Mine in Pinal County, Arizona, from Iporanga, Brazil, and the Tsumeb mine of Namibia.

Local attractions Library The Leadhills Miners' Library (also known as the Allan Ramsay (poet), Allan Ramsay Library or the Leadhills Reading Society), founded in 1741 by 21 miners, the local schoolteacher and the local minister, specifically to purchase a collection of books for its members’ mutual improvement — its membership was not restricted to the miners; several non-miners, such as William Symington, John Brown (physician, born 1810), John Brown (author of ''Rab and his Friends'') and James Braid (surgeon), James Braid, were also full members — houses an extensive antiquarian book collection, loca ...

Lanarkite
Lanarkite is a mineral, a form of lead sulfate with formula Pb2(SO4)O. It was originally found at Leadhills in the Scottish county of Lanarkshire, hence the name. It forms white or light green, acicular monoclinic prismatic crystals, usually microscopic in size. It is an oxidation product of galena Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.

Lead Minerals
Lead () is a chemical element; it has symbol Pb (from Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains and polyhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibia
Namibia, officially the Republic of Namibia, is a country on the west coast of Southern Africa. Its borders include the Atlantic Ocean to the west, Angola and Zambia to the north, Botswana to the east and South Africa to the south; in the northeast, approximating a quadripoint, Zimbabwe lies less than 200 metres (660 feet) away along the Zambezi, Zambezi River near Kazungula, Zambia. Namibia's capital and largest city is Windhoek. Namibia is the driest country in sub-Saharan Africa, and has been inhabited since prehistoric times by the Khoekhoe, Khoi, San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. From 1600 the Ovambo people#History, Ovambo formed kingdoms, such as Ondonga and Oukwanyama. In 1884, the German Empire established rule over most of the territory, forming a colony known as German South West Africa. Between 1904 and 1908, German troops waged a punitive ...

Tsumeb
Tsumeb (; ) is a city of around 35,000 inhabitants and the largest town in the Oshikoto Region, Oshikoto region in northern Namibia. Tsumeb, since its founding in 1905, has been primarily a mining town. The town is the site of a deep mine (the lower workings now closed) whose ore deposits with respect to variety, rarity and aesthetics of minerals have been listed among 100 geological heritage sites around the world by the International Union of Geological Sciences (IUGS). History The town was founded in 1905 by German South-West Africa, German colonial power and celebrated its 100th year of existence in 2005. The name Tsumeb is generally pronounced "SOO-meb". The name is not a derivative of German language, German, Afrikaans language, Afrikaans, or English language, English. It has been suggested that it comes from Khoekhoe language, Nama and means either "Place of the moss" or "Place of the frog".

Tiger Mine
The tiger (''Panthera tigris'') is a large cat and a member of the genus ''Panthera'' native to Asia. It has a powerful, muscular body with a large head and paws, a long tail and orange fur with black, mostly vertical stripes. It is traditionally classified into nine recent subspecies, though some recognise only two subspecies, mainland Asian tigers and the island tigers of the Sunda Islands. Throughout the tiger's range, it inhabits mainly forests, from coniferous and temperate broadleaf and mixed forests in the Russian Far East and Northeast China to tropical and subtropical moist broadleaf forests on the Indian subcontinent and Southeast Asia. The tiger is an apex predator and preys mainly on ungulates, which it takes by ambush. It lives a mostly solitary life and occupies home ranges, defending these from individuals of the same sex. The range of a male tiger overlaps with that of multiple females with whom he mates. Females give birth to usually two or three cubs that sta ...

Type Locality (geology)
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality. The concept is similar to type site in archaeology. Examples of geological type localities Rocks and minerals * Aragonite: Molina de Aragón, Guadalajara, Spain * Autunite: Autun, France * Benmoreite: Ben More (Mull), Scotland * Blairmorite: Blairmore, Alberta, Canada * Boninite: Bonin Islands, Japan * Comendite: Comende, San Pietro Island, Sardinia * Cummingtonite: Cummington, Massachusetts * Dunite: Dun Mountain, New Zealand * Essexite: Essex County, Massachusetts, US * Fayalite: Horta, Fayal Island, Azores, Portugal * Harzburgite: Bad Harzburg, Germany * Icelandite: Thingmuli (Þingmúli), Iceland * Ijolite: Iivaara, Kuusamo, Finland * Kimberlite: ...

Wanlockhead Beam Engine - Geograph
Wanlockhead is a village in Dumfries and Galloway, Scotland, nestling in the Lowther Hills and south of Leadhills at the head of the Mennock Pass, which forms part of the Southern Uplands. It is Scotland's highest village, the village centre being at an elevation of around above sea level. Some sources, including VisitScotland, cite an altitude of but the highest house in the village has been measured at . The village can be accessed via the B797, which connects it to the A76 near Sanquhar and the A74(M) motorway at Abington. History Wanlockhead takes its name from the Wanlock Water, a stream which rises in the remote hollow which forms the setting of the village. The village owes its existence to the lead and other mineral deposits found in the surrounding hills. These deposits were first exploited by the Romans, and from the 13th century they began to be worked again in the summer. The village was founded permanently in 1680 when the Duke of Buccleuch built a lead sme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
