| has gloss | (noun) a dark mineral consisting of oxides of yttrium and erbium and tantalum and other minerals fergusonite |
| has gloss | eng: Fergusonite is a mineral comprising a complex oxide of various rare earth elements. The chemical formula of fergusonite species is (Y,RE)NbO4, where RE = rare-earth elements in solid solution with Y. Yttrium is usually dominant (the species fergusonite-(Y)), but sometimes Ce or Nd may predominate in molar proportion (species fergusonite-(Ce) and fergusonite-(Nd)). All the other rare earth elements are present in subordinate amount, and tantalum substitutes for some of the niobium. The mineral has tetragonal crystal symmetry and the same structure as scheelite (calcium tungstate, CaW4), but can be metamict (amorphous) due to radiation damage from its small content of thorium. It is found as needle-like or prismatic crystals in pegmatite. It was named after British Politician and mineral collector Robert Ferguson of Raith... |

| has gloss | deu: Fergusonit, genauer α-Fergusonit ist ein weitverbreites Mineral aus der Mineralklasse der Sulfate etc., genauer der Molybdate, Wolframate und Niobate. Es sind insgesamt drei Minerale mit diesem Namen bekannt, das Fergusonit-Y, das allein aus Yttrium und Niobat besteht, das Fergusonit-Ce, bei dem zusätzlich noch Cer und Lanthan enthalten sind und das von der IMA nicht anerkannte Fergusonit-Nd, das zusätzlich Neodym und Titan enthält. Diese beiden sind jedoch deutlich seltener als Fergusonit-Y. |
