Exotic accesory minerals in layered chromitites of the Campo Formoso complex (Brazil)

The Campo Formoso stratiform intrusive complex, in Bahia State, Brazil, considered to be Paleoproterozoic age consist of a tabular body of ultramafic rocks about 40 km log and 100-1100 m. wide. Thick horizons of chromitite are exploited and the deposits are the richest in Brazil. The complex was int...

Description
Summary:The Campo Formoso stratiform intrusive complex, in Bahia State, Brazil, considered to be Paleoproterozoic age consist of a tabular body of ultramafic rocks about 40 km log and 100-1100 m. wide. Thick horizons of chromitite are exploited and the deposits are the richest in Brazil. The complex was intruded by the Campo Formoso calc-alkaline batholith, emplaced by the result of the Transamazonian collision-realated orogeny.
