Weathered, circular carbonatite complex, consisting of three separate deposits hosted in beforsite, glimmerite, sövite, and some pyroxenite. With a diameter of 4.5 km, the Barreiro complex is the world's largest niobium deposit. Ore reserves were estimated in the early 1980s at more than 450 million tonnes of Nb ore (2.5% Nb2O5, 4.4% REO), and about 0.8 million tonnes of laterite ore (13.5% REO, 2% Nb2O5, 0.05% U3O8).

Geochronology

Mineralization age: Late Cretaceous : 91.6 Ma to 82.8 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
