    Abstract

    Chemical and mineralogical studies undertaken on TaNb rutile from Peninsular Malaysia are discussed. NbTa rutile is found as grains in alluvial tin concentrates, mostly from the Western Tin Belt. Pure rutile shows tetragonal prismatic form but TaNb rutile, due to high degree of substitution of Ti by Nb and Ta, is distorted in its growth, resulting in "wedge" e(101) or "spear" s(111) terminations. Due to high Nb, Ta and Fe contents, NbTa rutile crystal is highly inhomogenous and magnetic. Polished sections reveal the presence of exsolution phases of columbite-ixiolite, cassiterite, pure rutile and inclusions of ilmenite. Bulk composition shows the presence of niobium (9-17% Nb2O5), tantalum (5-26% Ta2O5), iron (5-13% FeO), tin (2-7% SnO2), tungsten (0.5-1.0% WO3), manganese (0.2-1.0% MnO) and zirconium (0.0-0.2% ZrO2) in the dominantly Ti-bearing host.
