Native Vanadium
Native vanadium is the mineral form of the metal vanadium Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer ( pas ..., with the accepted name "vanadium". This exceedingly rare mineral was found among fumaroles of the Colima Volcano. Fumaroles of Colima are known of being vanadium-rich, depositing other vanadium minerals, that include shcherbinaite (V2O5) and colimaite (K3VS4).

Vanadium
Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer ( passivation) somewhat stabilizes the free metal against further oxidation. Spanish scientist Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by analyzing a new lead-bearing mineral he called "brown lead". Though he initially presumed its qualities were due to the presence of a new element, he was later erroneously convinced by French chemist Hippolyte Victor Collet-Descotils that the element was just chromium. Then in 1830, Nils Gabriel Sefström generated chlorides of vanadium, thus proving there was a new element, and named it "vanadium" after the Scandinavian goddess of beauty and fertility, Vanadís (Freyja). The name was based on the wide range of colors found in vanadium compounds. Del Rio's lead mineral was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcán De Colima
The Volcán de Colima, 3,820 m (12,533 ft), also known as Volcán de Fuego, is part of the Colima Volcanic Complex (CVC) consisting of Volcán de Colima, Nevado de Colima () and the eroded El Cántaro (listed as extinct). It is the youngest of the three and as of 2015 is one of the most active volcanos in Mexico and in North America. It has erupted more than 40 times since 1576. One of the largest eruptions was on January 20–24, 1913. Nevado de Colima, also known as Tzapotépetl, lies north of its more active neighbor and is the taller of the two at 4,271 meters (14,015 ft). It is the 26th-most prominent peak in North America. Despite its name, only a fraction of the volcano's surface area is in the state of Colima; the majority of its surface area lies over the border in the neighboring state of Jalisco, toward the western end of the Trans-Mexican Volcanic Belt. It is about west of Mexico City and south of Guadalajara, Jalisco. Since 1869–1878, a parasitic set of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colimaite
Colimaite, the naturally occurring analog of synthetic K3VS4, is a sulfide mineral discovered in southwestern Mexico. The potassium-vanadium sulfide was collected from the crater of the Colima volcano. The mineral colimaite is named after the locality of this volcanoOstrooumov, M., Taran, Y., Arellano-Jimenez, M., Ponse, A., and Reyes-Gasga, J. (2009) Colimaite, K3VS4 – anew potassium-vanadium sulfide mineral from the Colima volcano, State of Colima (Mexico) Revista Mexicana de Ciencias Geológicas, 26(3), 600-608 and has been approved in 2007, along with its mineral name, by the Commission on New Minerals, Nomenclature and Classification (CNMNC). It has been given the International Mineralogical Association number of IMA 2007–045. Composition The chemical formula of colimaite is K3VS4. The enrichment of vanadium in Colima's volcanic gases make it unique. The study of sulfur content in the fumaroles is also important, in order to know how an eruption could affect global cli ...

Native Element Minerals
Native element minerals are those chemical element, elements that occur in nature in Free element, uncombined form with a distinct mineral structure. The elemental class includes native metal, metals, intermetallic compounds, alloys, metalloids, and nonmetals. The Nickel–Strunz classification system also includes the naturally occurring phosphides, silicides, nitrides, carbides, and arsenides. Elements The following elements occur as native element minerals or alloys: Nickel–Strunz Classification -01- Native elements This list uses the Strunz classification, Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication). ;Abbreviations: * "*" – discredited (IMA/CNMNC status). * "?" – questionable/doubtful (IMA/CNMNC status). * "REE" – Rare-earth element (Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) * "PGE" – Platinum group, Platinum-group element (Ru, Rh, Pd, Os, Ir, Pt) * 03.C Aluminofluorides, 06 Borates, 08 Vanadates (04. ...
