“…At the basal portion, the supergroup includes the diamondiferous metaconglomerates and continental fluvial, fan-deltaic, and lacustrine quartzites represented by the São João da Chapada and Sopa-Brumadinho formations (Alkmim et al, 2006;Dussin and Dussin, 1995), both representing the Guinda Group (Knauer and Schrank, 1993). Upwards, the Espinhaço Supergroup includes the aeolian quartzites of Galho do Miguel Formation, overlaid by the Conselheiro Mata Group, which includes five formations, all deposited under marine conditions, and represented by metasiltstones, metadolomite and quartzite deposits (Almeida Abreu and Pflug, 1994;Silva and Chaves, 2012).…”
