The Peixe alkaline complex, primarily in Tocantins, Brazil is located at 12º 42’/13º00’ S -48º30’/48º38’ W

The Peixe Alkaline Suite comprises medium-grained foliated and banded leucocratic rocks represented by syenogranites, nepheline syenites, and alkaline pegmatites. These rocks exhibit recrystallized textures, with points in triple junctions, along with metamorphic albite and magnetite, indicating that they were subjected to low-grade metamorphism conditions. Leucogranites were formed during the Neoproterozoic, associated with the evolution of the Mara Rosa Magmatic Arc located only in the north of Goiás.
