Wodginite

	Wodginite Wodginite is a manganese, tin, tantalum oxide mineral with the chemical formula . It may also include significant amounts of niobium. Background Wodginite was first described in 1963 for an occurrence in the Wodgina pegmatite, Wodgina, Pilbara Region, Western Australia. Typical occurrence of Wodginite occurs in zoned pegmatites in amphibolite. It is associated with tantalite, albite, quartz, muscovite, tapiolite, microlite and microcline. It occurs in pegmatites in a wide variety of locations. The most studied is the Tanco pegmatite in Manitoba, Canada; also in Red Lake, Ontario. It is reported from the Strickland quarry, Portland, Middlesex County, Connecticut; the Herbb #2 pegmatite, Powhatan County, Virginia; the McAllister mine, Rockford, Coosa County, Alabama; the Peerless mine, Pennington County, South Dakota. Also from Paraíba and Minas Gerais, Brazil; Krasonice, Czech Republic; Orivesi, Finland; Kalba, eastern Kazakhstan; Ankole, Uganda; Miami district, Zimbabwe ...

	Tapiolite Tapiolite [(iron, Fe, manganese, Mn)(niobium, Nb, tantalum, Ta)2oxygen, O6] is a black mineral series that is an ore of niobium and tantalum. The tapiolite group includes tapiolite-(Fe) or ferrotapiolite and tapiolite-(Mn) or manganotapiolite. Tapiolite-(Fe) is by far the more common of the two. The minerals have a submetallic Lustre (mineralogy), luster and a high specific gravity with tapiolite-Fe having a higher specific gravity (7.90) versus 7.72 for tapiolite-Mn. The mineral was named in 1863 after the forest god Tapio (spirit), Tapio of Finnish mythology, and the original tapiolite material came from Sukula, Tammela, Finland, Tammela, Tavastia Proper, Finland. Tapiolite is very close to ''columbite'' and ''tantalite''. Those minerals have the same chemical composition, but different crystal symmetry orthorhombic for tantalite or columbite and tetragonal for tapiolite.P. Cerny et al.

	Minas Gerais Minas Gerais () is a state in Southeastern Brazil. It ranks as the second most populous, the third by gross domestic product (GDP), and the fourth largest by area in the country. The state's capital and largest city, Belo Horizonte (literally "Beautiful Horizon"), is a major urban and finance center in Latin America, and the sixth largest municipality in Brazil, after the cities of São Paulo, Rio de Janeiro, Salvador, Brasília and Fortaleza, but its metropolitan area is the third largest in Brazil with just over 5.8 million inhabitants, after those of São Paulo and Rio de Janeiro. Nine Brazilian presidents were born in Minas Gerais, the most of any state. The state has 10.1% of the Brazilian population and is responsible for 8.7% of the Brazilian GDP. With an area of —larger than Metropolitan France—it is the fourth most extensive state in Brazil. The main producer of coffee and milk in the country, Minas Gerais is known for its heritage of architecture and colonia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
