The Late Neoproterozoic–Cambrian Araçuaí orogeny encompasses the entire region between the São Francisco craton and the Atlantic continental margin in eastern Brazil. The crystalline core consists of high-grade rocks and granites exposed in eastern Minas Gerais and Espirito Santo and represents the internal part of the orogen. The granitic supersuites (G1 to G5) originated during the pre- to pos-collisional phase of the orogen (630-480 Ma). The G2 supersuite mostly consists of S-type granites formed during the syn-collisional stage (c. 585–560 Ma), and includes the Carlos Chagas batholith, Ataléia and Urucum suites and the Nanuque and Montanha plutons. The Carlos Chagas batholith is one of the largest S-type granites in the world with an area around 14000 km2. The main feature of the Carlos Chagas granite is the large and variable concentration of garnet (5 to 10 vol %) in the rocks. The main objective of this study is to understand the origin of the garnet crystals by studying their compositional and textural characteristics. To date, all studies that have examined the Carlos Chagas granite have assumed that the garnet crystals are of igneous origin.
