Composition of metamict zircon from Mozambique

Nine specimens of metamict zircon from granite pegmatites of the district of Zambézia, Mozambique, have been analyzed by wet chemical methods and by X-ray fluorescence. The specimens, which are contaminated by xenotime, display low densities and a low degree of order with only a few of the strongest...

description Nine specimens of metamict zircon from granite pegmatites of the district of Zambézia, Mozambique, have been analyzed by wet chemical methods and by X-ray fluorescence. The specimens, which are contaminated by xenotime, display low densities and a low degree of order with only a few of the strongest zircon lines in the X-ray powder pattern. The mineral apparently crystallized in open wugs. The high water content is considered interstitial incorporated in the structure, not as -(OH)-4 replacing SiO4. The incorporation of water into the structure may have been simultaneous with the crystallization and metamictization of the mineral.
