Influência da pressão e temperatura na cristalinidade da illita em sequências Proterozoicas: Norte do Distrito Federal e Goiás, Brasil

Abstract: As sequências Proterozoicas, ao Norte no Distrito Federal e na região de Bezerra e Vila Boa (Goiás), são constituídas por calcários e dolomitos, pelitos e arenitos correspondentes aos Grupos Bambuí e Paranoá. No Distrito Federal, tais unidades são sobrepostas tectonicamente por rochas metassedimentares de fácies xisto-verde do Grupo Canastra. Entre os constituintes minerais dos termos pelíticos de todas estas unidades, predominam os filossilicatos, particularmente a illita e a muscovita, identificados por difr… Show more

“…Over the years, many proposals on the hierarchy of the deformation phases in the Southern Brasília Belt have been discussed (Campos Neto 1984a, Pinho et al 1989, 1990, Pinho 1990, Pereira 1992, Pinho & Dardenne 1993, Rostirolla et al 2002, and will be detailed further in this work. In addition, new knowledge (Campos et al 2015) related to the metamorphic conditions was accepted by recent studies of X-ray diffraction (XRD) in the rocks from the Canastra Group, located in Distrito Federal and Goiás state (Fig. 1B).…”
