Duftite
Duftite is a relatively common arsenate mineral with the formula CuPb(AsO4)(OH), related to conichalcite. It is green and often forms botryoidal aggregates. It is a member of the adelite-descloizite Group, Conichalcite-Duftite Series. Duftite and conichalcite specimens from Tsumeb are commonly zoned in color and composition. Microprobe analyses and X-ray powder-diffraction studies indicate extensive substitution of Zn for Cu, and Ca for Pb in the duftite structure. This indicates a solid solution among conichalcite, CaCu(AsO4 )(OH), austinite, CaZn(AsO4)(OH) and duftite PbCu(AsO4)(OH), all of them belonging to the adelite group of arsenates. It was named after Mining Councilor G Duft, Director of the Otavi Mine and Railroad Company, Tsumeb, Namibia. The Type locality (geology), type locality is the Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia. Structure The structure is composed of chains of edge-sharing CuO6 distorted octahedra parallel to the c axis. The chains are linked by As ...

Germanium
Germanium is a chemical element; it has Symbol (chemistry), symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid or a nonmetal in the carbon group that is chemically similar to silicon. Like silicon, germanium naturally Chemical reaction, reacts and forms complexes with oxygen in nature. Because it seldom appears in high concentration, germanium was found comparatively late in the Timeline of chemical element discoveries, discovery of the elements. Germanium ranks 50th Abundance of elements in Earth's crust, in abundance of the elements in the Earth's crust. In 1869, Dmitri Mendeleev Mendeleev's predicted elements, predicted its existence and some of its Chemical property, properties from its position on his periodic table, and called the element ekasilicon. On February 6, 1886, Clemens Winkler at Freiberg University found the new element, along with silver and sulfur, in the mineral argyrodite. Winkle ...

Hoba Meteorite
The Hoba ( ) meteorite is named after the farm Hoba West, where it lies, not far from Grootfontein, in the Otjozondjupa Region of Namibia. It has been uncovered, but because of its large mass, has never been moved from where it fell. The main mass is estimated at more than 60 tonnes. It is the largest known intact meteorite (as a single piece) and about twice as massive as the largest fragment of either the Cape York meteorite's 31-tonne Ahnighito kept in the American Museum of Natural History or the Campo del Cielo's 31-tonne Gancedo (meteorite), Gancedo in Argentina. It is also the most massive naturally occurring piece of iron (specifically ferronickel) known on Earth's surface. The name ''Hoba'' comes from a Khoekhoe language, Khoekhoegowab word meaning 'gift'. Following its donation to the government in 1987, a visitor centre was constructed with a circular stone access and seating area. Impact The Hoba meteorite is thought to have impacted Earth less than 80,000 years ago. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
