1. Depicting the 3D geometry of ore bodies using implicit lithological modeling: An example from the Horto-Baratinha iron deposit, Guanhães block, MG
Abstract The definition of geological domains is essential for mineral exploration and is traditionally done manually, section by section, in a laborious, time consuming and subjective process, to construct a 3D model. The technique referred to as implicit modeling is an option to model deposits in a fast and practical manner. This article presents the litho

2. Geocronologia da região de Gondola-Nhamatanda (Centro de Moçambique) / não informado
The region of Gondola-Nhamatanda is located at the border between the provinces of Manica and Sofala, central part of Moçambique. It is geologically inserted in the Bárue complex and the Phanerozoic cover. The Bárue complex is composed of the Macossa and Chimoio supracrustal groups intruded by plutonic rocks of various compositions, whereas the Phanerozoi

3. Estratigrafia e petrogênese das sequências vulcânicas paleoproterozóicas na região de São Félix do Xingu (PA), Província Mineral de Carajás / Stratigraphy and petrogenesis of the paleoproterozoic volcanic sequences in the São Félix do Xingu (PA) region, Carajás Mineral Province
Near the São Félix do Xingu city, centersouth portion of the Pará state, in the context of the Carajás Mineral Province, occur extensive Paleoproterozoic volcanoplutonism (1.88 1.87 Ga) exceptionally well-preserved and grouped in the Sobreiro and Santa Rosa formations. These suites are generically correlated to Uatumã Supergroup volcanoplutonism, a magm

4. Análise tectono-estratigráfica da Faixa de dobramento Paraguai meridional na Serra da Bodoquena e depressão do Rio Miranda, MS / Tectonostratigraphic analysis of the southern Paraguay fold belt in Serra da Bodoquena and Rio Miranda depression, MS
This work aims to characterize the geological and structural context of the Southern Paraguay Folded Belt, and to understand the stratigraphic relationships between the Puga Formation, Corumbá and Cuiabá groups. Regional geological reconnaissance work and detailed geological-structural field sections were carried out, with petrographic and structural analy

5. Estruturas tectônicas cenozóicas na porção leste da Bacia Potiguar - RN
This thesis encompasses the integration of geological, geophysical, and seismological data in the east part of the Potiguar basin, northeastern Brazil. The northeastern region is located in South American passive margin, which exhibits important areas that present neotectonic activity. The definition of the chronology of events, geometry of structures genera

6. Structural geology of northern limb of the Paraiba do Sul river divergent structure: cross-sections Três Rios (RJ) - Matias Barbosa (MG) and Barra do Piraí - Conservatória (RJ) / Geologia estrutural da aba norte da estrutura divergente do rio Paraíba do Sul: seções Três Rios (RJ) - Matias Barbosa (MG) e Barra do Piraí - Conservatório (RJ)
This study is about the structural geology of a portion of the Central Mantiqueira Province which corresponds to the north side of the structural divergence of the Rio Paraíba do Sul valley. Two geological cross-sections (Três Rios - Matias Barbosa and Barra do Piraí - Conservatória) provided geometrical and kinematics data. Lattice preferred orientation

7. Zoneamento ambiental da área de expansão urbana da Caldas Novas GO: procedimentos e aplicações
This study aimed at understanding the dynamics of the urban physical environment of Caldas Novas GO, and its relation to the use and occupation. In order to accomplish this, the attributes of the physical environment related to the bedrock and unconsolidated materials, the water table depth, the declivity, the average annual rain fall in the scale of 1:25.00

8. High resolution stratigraphy framework for carbonatic deposits of terciary of the Basin Campos / Geração de um arcabouço estratigráfico de alta resolução para depósitos carbonáticos terciários da Bacia de Campos
The Siri Member is of great importance due to the heavy oil content that is present on the carbonate platform developed during the Tertiary. Considering this importance, we conducted a study with the objective of generating a high resolution stratigraphic framework, on 3rd order sequences, using the interpretation of two seismic sections and the analysis of

9. Evolução tectono-estrutural do Campo de Xaréu (Sub-bacia de Mundaú, Bacia do Ceará - NE do Brasil: abordagem multiescala e pluriferramental
The Xaréu Oil Field, located in the center-southern portion of the Mundaú Sub-Basin (eastern portion of the Ceará Basin), is characterized by a main Iramework of NW-trending and NE-dipping faults. The faults in the Xaréu Oil Field, among which the Xaréu Fautt stands out, are arranged according to an extensional-listriclan, rooted on a detachment surface

10. Alto Guaratuba s river capture: a methodological proposal for the study of relief evolution in Serra do Mar, Boracéia-SP. / A captura do Alto Rio Guaratuba: uma proposta metodológica para o estudo da evolução do relevo na Serra do Mar, Boracéia - SP.
Este trabalho trata da captura da bacia do Alto Guaratuba, devido ao recuo da Escarpa da Serra do Mar na região de Boracéia-SP. A bacia do Alto Guaratuba localiza-se no reverso imediato da Escarpa da Serra do Mar, a aproximadamente 45056 e 45052 de longitude oeste e 23038 e 23042 de latitude sul, onde situa-se a Estação Biológica de Boracéia (U

Integração digital de imagens de radar e LANDSAT-TM com dados geológicos e aerogamaespectrométricos no auxílio ao mapeamento geológico da região do Complexo Granítico Estrela - Pará (PA) / Radar, geologic, airborne gamma ray and LANDSAT-TM digital data integration for geological mapping of the Estrela Granite Complex (PA).
This work is focused on the geotectonic context of the Carajás Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the tecno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite C
