  • Fergusonite - Wikipedia

    en.wikipedia.org/wiki/Fergusonite There are Fergusonite-beta-(Nd), Fergusonite-beta-(Y), Fergusonite-beta-(Ce) forms too, but they are classified as 4.DG.10 in the Nickel–Strunz system. The mineral has tetragonal crystal symmetry and the same structure as scheelite (calcium tungstate, CaWO 4 ), but can be metamict (amorphous) due to radiation damage from its small content of ...
