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 …

Relatively rare, tantalum is about as abundant as uranium.It occurs, with niobium, in the columbite–tantalite series (in which columbite [FeNb 2 O 6] and tantalite [FeTa 2 O 6] occur in highly variable ratios) and the pyrochlore–microlite series of minerals. Native tantalum metal with some niobium and traces of manganese and gold occurs sparingly …
