Tantalite has a dimorphic relationship to another mineral called tapiolite. A dimorph is a mineral that has the same chemistry but a different structure. Tapiolite has a tetragonal structure as opposed to the orthorhombic structure of tantalite although it has exactly the same chemistry, (Fe, Mn)(Ta, Nb)2O6.

Tantalite, [(Fe, Mn) Ta2O6], is a mineral that is close to columbite. In fact, the two are often grouped together as a semi-singular mineral called columbite-tantalite in many mineral guides. ... Tantalite is black to brown in both color and streak. Manganese rich tantalites can be brown and translucent.
