RC Ewing - Canadian Mineralogist, 1976 - canmin.geoscienceworld.org ABSTRACT Since their initial description in the early l80o's, orthorhombic,
rare-earth, ABsOa-tyW, Nb-Ta-Ti oxides have been a "mineralogical headache". Due
to complex compositions, their metamict state and pervasive alteration, as ... Cited by 13 - Related articles
