Abstract: Niobium-Tantalum minerals found in concentrates and heavy minerals from Peninsular Malaysia have been studied, and their mode of occurrences described. Chemical compositions were determined mainly by Electron-probe microanalysis, but X-ray fluorescence method has also been applied. From the study, columbite-tantalite, Nb- Ta- rutile, wodginite and fersmite have been recognised. Their geographical distribution and geochemical compositions were delineated.
