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 ...

Oxide Mineral
The oxide mineral class includes those minerals in which the oxide anion (O2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class.

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 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 of Finnish mythology, and the original tapiolite material came from Sukula, Tammel ...

Red Lake, Ontario
Red Lake is a municipality with town status in the Canadian province of Ontario, located northwest of Thunder Bay and less than from the Manitoba border. The municipality consists of six small communities—Balmertown, Cochenour, Madsen, McKenzie Island, Red Lake and Starratt-Olsen—and had a population of 4,107 people in the Canada 2016 Census. Red Lake is an enclave within Unorganized Kenora District. The municipality was formed on 1 July 1998, when the former incorporated townships of Golden and Red Lake were merged along with a small portion of Unorganized Kenora District. The name of the town comes from a local legend telling of two men from the Chippewa tribe who stumbled across a large moose. The men proceeded to kill the moose, the blood of which drained into a nearby lake. The blood turned the lake's waters red in colour, ultimately giving the area its name. The name appears on the Bouchette map of 1875, and was officially approved on 7 December 1909. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
