An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Kassite is a rare mineral whose chemical formula is CaTi2O4(OH)2. It crystallizes in the orthorhombic crystal system and forms radiating rosettes and pseudo-hexagonal tabular crystals which are commonly twinned. Kassite crystals are brownish pink to pale yellow in color, are translucent, and have an adamantine luster. Cleavage is distinctly visible, and the crystals are very brittle.

  • La kassita és un mineral de la classe dels òxids. Va ser anomenada en honor de Nikolai Grigor’evich Kassin (1885–1949), el geòleg que va descobrir el massís d'Afrikanda, on es troba la localitat tipus d'aquest mineral. (ca)
  • Kassit ist ein sehr selten vorkommendes Mineral aus der Mineralklasse der „Oxide und Hydroxide“ mit der chemischen Zusammensetzung CaTi2(OH)2O4 und ist damit chemisch gesehen ein basisches Calcium-Titan-Oxid. Kassit kristallisiert im orthorhombischen Kristallsystem und entwickelt nach der b-Achse abgeflachte, blättrige und pseudohexagonale Kristalle von bis zu einem Millimeter Größe und diamantähnlichem Glanz auf den Oberflächen. Die durchscheinenden Kristalle sind von braunroter oder hellgelber Farbe und oft zu rosettenförmigen Mineral-Aggregaten angeordnet sind. Auch farblose Kassite sind bekannt. (de)

  • Kassite is a rare mineral whose chemical formula is CaTi2O4(OH)2. It crystallizes in the orthorhombic crystal system and forms radiating rosettes and pseudo-hexagonal tabular crystals which are commonly twinned. Kassite crystals are brownish pink to pale yellow in color, are translucent, and have an adamantine luster. Cleavage is distinctly visible, and the crystals are very brittle. It was first described in 1965 in the Afrikanda pyroxenite massif, a formation on Russia's Kola Peninsula and was named for (1885–1949), a prominent Russian geologist. It occurs as miarolytic cavity fillings of alkalic pegmatites in the Kola occurrence and in nepheline syenite in the Magnet Cove igneous complex of Arkansas, US. Its mineral association includes cafetite (which with it is also polymorphous), perovskite, titanite, rutile and ilmenite. (en)
