Columbite - an overview ScienceDirect Topics

Rare examples of columbite–tantalite, ideally (Mn,Fe)(Nb,Ta) 2 O 6, were reported to contain enough U to induce amorphization (see Lumpkin 102 and references to previous work). These ∼1800 Ma samples are zoned in both the TiO 2 (2.2–4.8 wt%) and UO 2 (0.2–2.6 wt%) contents and exhibit a critical amorphization dose of 8 × 10 16 α per ...
