2. Processamento e modelagem de dados geofísicos e imagens ASTER aplicados à interpretação geológica e prospecção mineral na Província Aurífera de Alta Floresta, MT / Processing and modeling of geophysical data and ASTER images applied to geological interpretation and mineral exploration in the Alta Floresta Gold Province, MT
The Alta Floresta Gold Province (AFGP) is located in the central-southern Amazon craton between the limits of the Ventuari-Tapajos (1.95-1.8 Ga) and Rio Negro-Juruena (1.8-1.55 Ga) provinces. In its eastern segment there are more than one hundred gold deposits hosted in volcanic and plutonic rocks and concentrated along the Peru-Trairao Belt in a NW-SE direc

3. Evolução magmática, alteração hidrotermal e gênese da mineralização de ouro e cobre do Palito, Província Aurífera do Tapajós (PA) / Magmatic evolution, hydrothermal alteration and geneseis of gold-copper mineralization at Palito, Tapajós Gold Province (PA)
The Palito porphyry type copper-gold deposit is located in the central region of the Amazonian craton, in the Tapajós Gold Province (TGP), in an area that is dominated by intermediate to felsic granitic and volcanic rocks of late Paleoproterozoic age. Three lithotypes make up this deposit. The Palito Granite, with porphyritic features, is the host rock for

4. Características epigenéticas do depósito de cu-au chapada, arco magmático de goiás
The Cu-Au Chapada deposit is located from 8km of Alto Horizonte-GO. The geologic picture is dominated by metavulcanic sedimentary sequences that integrate the Neoproterozoic Magmatic Arc of Mara Rosa, located in the central portion of the Tocantins Province. The framework of the deposit is represented by an antiform whose core is composed by association of t

5. Evolução quimica e isotopica dos fluidos associados a mineralização de Fe-Cu-Au do deposito Alvo 118, provincia mineral de Carajas - PA / Chemical and isotopic evolution of the fluids from the Alvo 118 Fe-Cu-Au do deposit, Carajas mineral province (PA)
The Alvo 118 iron oxide-copper-gold (IOCG) deposit (170 Mt @ 1,0 wt% Cu, 0,3 g/t Au), together with the world-class Sossego and Cristalino deposits, lie in the southern sector of the Carajas Mineral Province (CMP) along a steeply-dipping, WNW-ESE-striking, 60 km-long shear zone, close to the contact of the Itacaiunas Supergroup metavolcano-sedimentary sequen

6. Processos metalogenéticos em ambientes de arco magmático tipo andino, caso de estudo: mineralizações da região dos Andes Patagônicos setentrionais do Chile / Metallogenic processes in andean volcanic arc setting, study case: mineralizations in the Chilean North-Patagonion Andes
In the Patagonian Andes region between 41 and 44° S extensive and continuous plutonic rocks of the North-Patagonian Batholith north segment are exposed. During their evolution most of the granitic rocks were emplaced in metamorphic rocks and other parts were emplaced in Late Jurassic-Berriasan volcanic rocks, Early Cretaceous sedimentary and volcanic rocks,

7. InterpretaÃÃo sÃsmica e modelamento magnetomÃtrico e gravimÃtrico 2D e 3D de corpos vulcÃnicos localizadosna sub-bacia do Platà de Pernambuco: uma contribuiÃÃo Ãsua evoluÃÃo tectono-estratigrÃfica
A Sub-bacia do Platà de Pernambuco à uma das Ãltimas porÃÃes sedimentares percebidas e descritas na literatura, e certamente uma das Ãltimas a ser formada durante a separaÃÃo das placas Sul-Americana e Africana. Ela corresponde à sub-bacia offshore da Bacia de Pernambuco e à marcada por grande proporÃÃo de derrames vulcÃnicos ocasionados provave

8. EVOLUÇÃO TECTONOSSEDIMENTAR DA BACIA DOS PARECIS AMAZÔNIA
The Parecis basin is located in central-western Brazil, on the southwestern part of the Amazon craton, between the Rondônia and Guaporé fold belts. From west to east, the Parecis basin can be divided into three tectono-sedimentary domains: a tectonic low to the west, a central compartment characterized by a negative gravimetric anomaly, and a interior sag

10. Seismic interpretation of post-aptian magmatic events in the Cabo Frio high, Southeast Brazil, its genesis and its relation with pre-salt alignments / Interpretação sísmica dos eventos magmáticos pós-aptianos no alto de Cabo Frio, sudeste do Brasil, gênese e relação com os lineamentos pré-sal
The continental shelf of the Cabo Frio Area, at the southern part of the Campos Basin, shows unique features in its tectono-sedimentary evolution when compared to other areas of the Campos and Santos basins. The presence of a regular pattern of antithetic faults in the basement and in the syn-rift and the post-rift sedimentary sections, along with important

11. 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

12. Petrogenese das intrusões graniticas compostas de Teofilandia e Barrocas, Greenstone Belt do Rio Itapicuru, Bahia, Brasil
The Rio Itapicuru Greenstone Belt (RIGB) is a Paleoproteozoic sequence situated in the northern portion of the São Francisco Craton, Bahia state, Brazil. Overlying a basement consisting of gnaisse and migmatites, this volcanic-sedimentary belt is intruded by several granitoid intrusions of different chemical compositions. Two of the most important intrusive
