Thorium deposit, consisting of magnetite stockworks in highly weathered alkaline rocks. The deposit was studied as a natural analogue for nuclear waste disposal. Once the world's largest baddeleyite deposit, but now depleted.
Originally known as "Morro Alto e Consulta".

1600 - 2500 Ma
|Paleoproterozoic intrusive and metamorphic terranes|
Age: Proterozoic (1600 - 2500 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
