• Mineralogy of Tin and Niobium-Tantalum-Bearing Minerals in

    In general columbite-tantalite in Thailand contains higher Ta than Nb and tends to be high in Fe in the north whereas in the south Mn is predominant. In Malaysia columbite as well as ferro-columbite is more common than tantalite. In the southern part (Bakri) Mn-tantalite with Ta-rich series such as wodginite and tapiolite are also observed.

  • Occurrence and Composition of Columbite-(Fe) In the

    Columbite-(Fe) is a post-magmatic accessory mineral occurring within syenogranites and greisens from the Desemborque Pluton. The petrographic (SEM) and geochemical (EPMA and LA-ICPMS) examination of this mineral shows two distinct textural types within both the rocks named columbite-1 and columbite-2. The columbite-1 type is characterized by zoned crystals with two stages of crystallization
