Campo Belo Metamorphic Complex: tectonic evolution of an Archean sialic crust of the southern São Francisco Craton in Minas Gerais (Brazil)

Abstract: Systematic geological studies performed in the study area allowed the characterization of six lithodemic units: three gneissic, one amphibolitic, one supracrustal and one fissure mafic. The mineral assemblage and the structural record of these lithodemic units indicate that the study area was affected by five tectonothermal events. The structural pattern of the first and oldest event occurred under granulite facies conditions and reveals essentially a sinistral kinematic pattern. The second event, showing domi… Show more

“…A região de Cláudio (Figura 1), porção sul do estado de Minas Gerais, pertence a este contexto geológico, sendo constituída por rochas gnáissicas, anfibolíticas e metaultramáficas (metaperidotitos, metapiroxenitos) que foram intrudidas por gabronoritos, granitóides e gabros (Carneiro et al,1996). Oliveira & Carneiro (2001) dividem a região em unidades gnáissica, anfibolítica, supracrustal e máfica fissural (Figura 2). A unidade gnáissicaé representada por rochas de composição variando de tonalitos a granitos.…”
