1. Characterization of Sobradinho landslide in fluvial valley using MASW and ERT methods
Abstract Landslides can substantially impact the fluvial systems, which is why the continuous mapping of their extent, evolution and stability assessment is crucial. However, in such environments, material identification (e.g. colluvium) and subsurface characterization by the methods used for geologic mapping and geotechnical investigation is often a challen

2. Integrating geological and airborne geophysical data to review the cartography of Rio Itanguá Batholith, Araçuaí Orogen, Brazil
ABSTRACT Rio Itanguá Batholith (RIB) is a plutonic body located in the Northern border of Guanhães block, one of the various basement blocks reworked within the Araçuaí orogen, Eastern Brazil. Although its existence is known since the beginning of the 20th century, its tectonic history remains poorly understood. The RIB was mapped at 1:100,000 scale in t

3. 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

4. Influência de níveis de base nas características morfossedimentares das bacias dos rios das Velhas e Jequitaí (MG)
The Velhas and Jequitaí river basins have together an asymmetric shape that drain northward from Quadrilátero Ferrífero to the northern Minas Gerais State. These two basins are affluent of São Francisco river in its right margin. The headwaters of Velhas and Jequitaí rivers are dominated by quartzites ridges structured during the Brazilian orogenic cycl

5. 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

6. FAULT MESHING GENERATION IN SEISMIC DATA BY COMPETITIVE LEARNING / GERAÇÃO DE MALHAS DE FALHAS EM DADOS SÍSMICOS POR APRENDIZADO COMPETITIVO
Manual fault mapping from 3D seismic data is a time-consuming task. A plethora of seismic attributes has been proposed to enhance the discontinuity measures associated with faults. However, faults viewed through these attributes appear more like trends than well-defined, continuous surfaces, posing obstacles to the automation of the fault modeling process. T

7. Mapeamento do potencial mineral para niquel e ouro no Cinturão Metassedimentar Nova Brasilandia - Rondonia por meio de logica nebulosa (fuzzi) e redes neurais artificiais / Mineral potential mapping for nickel and gold in Nova Brasilandia Metassedimentar Belt - Rondonia trough fuzzy logic and artificial neuraL networks
Analysis and integration of spatial data from different natures, particularly on Geographic Information Systems (GIS), is a well known technique in mineral prospection. The available tools and other ones recently developed can help prospection campaigns where there is not enough geologic and metalogenetic knowledge, as the Nova Brasilândia Metassedimentar B

8. Evolução estrutural brasiliana da Província Borborema na região de Campina Grande, (PB) / Brasilian structural evolution of Borborema Province in the Campina Grande region (PB)
The systematic mapping of Campina Grande sheet (1:100.000) is very important to understand the structural and geochronological relations between different terranes of the Transversal Zone, Borborema Province (NE Brazil). The mapped area is an excellent natural laboratory to apply classical and modern techniques of structural geology for the study of mechanis

9. Airbone geophysical and geologic data integration and its contribution the geodynamic evolution of central Ceara domain, Borborema Province / Integração de dados aerogeofisicos e geologicos e sua contribuição a evolução geodinamica do dominio Ceará Central, Provincia Borborema
Advances in airborne geophysical data processing techniques and their integration with geologic data allow recovering valuable information from both geophysical surveys and, the older technology. These information represent an essential tool for geologic-structural mapping of Pre-Cambrian terrains, where the stratigraphic and structural relations are difficu

10. Mapeamento do potencial de instabilização de taludes rodoviários usando SIG e seções geológico-geotécnicas de campo com aplicação na rodovia SP-310 / Mapping of the potential of instabilization of road slopes using Sig and geological-geotecnical sections of field with application in highway SP-310
The present study developed a methodology for mapping of instability potential of road slopes. It was used, for in such a way, GIS (Geographic Information System) and obtained geologic-geotechnical of detail sections in surface surveys. This methodology was used in a section of Road Washington Luís (SP-310), under two different conditions. First, it was app
