In the Araxá Group metasediments in southern Goiás, there are occurences of numerous gnaissified granitic bodies. Two of these occurrences are located near Rochedo district, municipality of Piracanjuba. These two occurences show peraluminous, calc-alkaline composition, and are classified as S-type and/or MPG. These orthogneissic bodies have low to medium levels of alkalis, enrichment in large ion lithophile elements (Cs, Th, U, Ba, Rb, K), and LREE relative to HREE and to high field strength elements (Zr, Y , Nb, Ta, Hf). They also show negative anomalies of Nb, Ta, P and Ti, similar to the chemical composition of magmas generated in magmatic arcs. The geochemical similarity in the distribution patterns of LILE, HFSE, REE and the presence o...
