Resumo

The two largest gabbro-peridotite-anorthositic Complexes presently recognized in Brazil, the Barro Alto and the Tocantins Complexes, outcrop in the central region of the Goiás State. They are believed to be Early Precambrian in age. The two complexes contain the same suite of rocks and have similar chemical, textural and mineralogical aspects. Stratiform and alpine features are present in both complexes.
