Three main types of niobium/tantalum deposits are distinguished: carbonatite complexes, alkaline to peralkaline rocks and pegmatites. All three deposit types have in common that they are hosted in rocks that preferentially accommodate incompatible elements such as niobium, rare earth elements etc. which do not occur in common rock forming minerals.

Carbonatite Wikipedia

Carbonatite (/ k ɑːr ˈ b ɒ n ə t aɪ t /) is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50% carbonate minerals. Carbonatites may be confused with marble and may require geochemical verification.. Carbonatites usually occur as small plugs within zoned alkalic intrusive complexes, or as dikes, sills, breccias, and veins.
