13. Geology and metallogenetic potential of the anorthositic-leucogabbroic Lagoa da Vaca Complex, Curaça, Bahia State, Brazil / Geologia e potencial metalogenetico do complexo anortositico-leucogabroico de Lagoa da Vaca, municipio de Curaça, Bahia
The complex is one of the three litho-structural domains mapped (central domain), and has an outcrop width of 3 kilometers. It is made up mostly of north-south-trending layers of anorthositic, meta-leucogabbroic, meta-gabbroic and ultramafic compositions. Ultramafic rocks of unknown stratigraphic relations, vz. peridotite and amphibole meta-peridotite, were

14. Tectonic evolution of the Maranco-Poço Redondo Domain : records of the Cariris Velhos and Brasiliano orogenesis on the Sergipano belt, NE Brazil / Evolução tectonica do dominio Maranco-Poço Redondo : registro das orogeneses Cariris Velhos e Brasiliana na Faixa Sergipana, NE do Brasil
This Thesis aims to advance in the geological knowledge of the Sergipano Belt, by studying the tectonic evolution for two within seven lithotectonic domains: the Marancó -Poço Redondo Domain. To reach the objective a detailed field work, that used four geological maps (1:100.000) from the Carira Project (PLGB, DNPM-CPRM, 1988) as base maps and a Landsat im

15. Genese dos depositos auriferos em metaconglomerados da formação moeda, Quadrilatero Ferrifero, MG : o papel do metamorfismo e associação com a materia carbonosa / Genesis of the metaconglomerate-hosted gold deposits of the moeda formation, Quadrilatero Ferrifero (State of Minas Gerais) : role of the metamorphism and the association with carbonaceous matter
The Quadrilátero Ferrífero has historically been one of the most important gold province in Brazil, with a significant number of productive greenstone-hosted lode gold deposits within the Rio das Velhas Supergroup together with those associated with the metasedimentary sequence of the Minas Supergroup. At the base of the Moeda formation, Minas Supergroup,

16. Geologia, Geocronologia, Geoquímica e Petrogênese das Rochas Ígneas Cretácicas da Província Magmática do Cabo e suas Relações com as Unidades Sedimentares da Bacia de Pernambuco (NE do Brasil)
The area studied forms a thin NNE-directed belt situated south of Recife town (Pernambuco state), northeastern Brazil. Geologically, it comprises the Pernambuco Basin (PB), which is limited by the Pernambuco Lineament to the north, the Maragogi high to the south and the Pernambuco Alagoas massif to the west, all of them with Precambrian age.
