1. Survey and study of graphite occurrences in the Aracoiába-Baturité graphite bearing District, CE / Levantamento e estudo das ocorrências de grafita do Distrito Grafitífero Aracoiába-Baturité, CE
The Aracoiába-Baturité Graphite-bearing District has graphitic gneiss deposits (disseminated ore) and vein (solid ore) with different genetic origins and their own physical characteristics and geological environments. The graphite gneiss ore is of sedimentary, syngenetic origin, with 1.5% to 8% C content, which is distributed along two long parallel belts,

2. Isótopos de carbono em filitos carbonosos da sequência metavulcano-sedimentar Marmeleiro, Sul de Ibaré, Rio Grande do Sul
Carbon isotope ratios for carbonaceous material in the graphite prospect of Marmeleiro Sequence, southwestern of the Sul-rio-grandense Shield, have been determined. The results are approximately constant with d13C-values between -27 and -24 per mil. These values suggest that the studied carbonaceous rocks were formed from syngenetic organic detritus, which w
