The quartz fabric indicates that prism {1000} slip was important during the deformation. This studies have showed that IJSZ changed from deeper crustal levels (12-15km) and ductile conditions to upper levels of about 4 to 6km and brittle strain conditions. -English summary141-153porcataclasitefabricfeldsparfluid inclusionmylonitequartzshear zoneBrazil, Sao PauloArtigoAcesso restrito2-s2.0-002779852010401359359087340000-0003-2125-3050
