The Carbonatite-Related Morro do Padre Niobium Deposit, Catalão II Complex, Central Brazil
Economic Geology, 2022The Morro do Padre deposit contains a valuable niobium resource estimated at 14.5 Mt at 1.52 wt % Nb2O5 (at a cut-off grade of 0.5% Nb2O5) hosted in carbonatite-related rocks and their regolith in the southern part of the Catalão II Complex, in central

Carbonatites and related alkaline rocks host most REE resources. Phosphate minerals, e.g., apatite and monazite, commonly occur as the main REE-host in carbonatites and have been used for tracing magmatic and mineralization processes.
