Tantalite
The decrease of Nb/Ta in columbite– tantalite and of Zr/Hf in zircon is consistent with fractionation of a silicate melt (Linnen and Keppler, 1997, 2002). The most contentious question concerning the magmatic controls of mineralization is how the ore minerals, primarily columbite–tantalite, become saturated.
