Pentlandite — Wikipédia

The pentlandite group is a subdivision of rare minerals that share similar chemical and structural properties with pentlandite, hence the name. Their chemical formula can be written as XY8(S, Se)8 in which X is usually replaced by silver, manganese, cadmium, and lead, while copper takes the place of Y. Iron, … Zobraziť viac Pentlandite is an iron–nickel sulfide with the chemical formula (Fe,Ni)9S8. Pentlandite has a narrow variation range in nickel to iron ratios (Ni:Fe), but it is usually described as 1:1. In some cases, this ratio is skewed by the … Zobraziť viac Pentlandite is the most common terrestrial nickel sulfide. It typically forms during cooling of a sulfide melt. These sulfide melts, in turn, are typically formed during the evolution of a silicate melt. Because nickel is a chalcophile element, it has preference for … Zobraziť viac • Pentlandite specimen from the Sudbury Basin in Ontario, Canada • Pentlandite specimen from Kambalda, Western Australia Zobraziť viac It is named after the Irish scientist Joseph Barclay Pentland (1797–1873), who first noted the mineral at Sudbury, Ontario. Zobraziť viac Physical & Optical Properties In the field, pentlandite is often confused with other sulfide minerals, as they are all brassy yellowish in color and have a metallic luster. For this reason, the best way to discern pentlandite is by its paler color, lack of … Zobraziť viac Pentlandite is found within the lower margins of mineralized layered intrusions, the best examples being the Bushveld igneous complex, South Africa, the Voisey's Bay troctolite intrusive complex in Canada, the Duluth gabbro, in North America, and various other … Zobraziť viac • Glossary of meteoritics • Ore genesis • Igneous differentiation Zobraziť viac WebPentlandite is a mineral consisting mainly of iron-nickel sulfide, in which the ratio of nickel to iron is usually close to 1:1.
