1. 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

2. Structural and mineralochemical characterization of a pegmatite deposit in the Santa Rosa Pegmatite Field, Minas Gerais Brazil
Abstract The Santa Rosa Pegmatite Field (SRPF), in northeastern Minas Gerais State, is one of the most important gemstone sources in Brazil. The economy of several neighboring cities greatly relies on the trade of its gemstones. However, efforts to improve gemstone mining with practical, scientific methods are scarce, making it a yet inexpensive, marginally

4. Upper Cretaceous weakly to strongly silica-undersaturated alkaline dike series of the Mantiqueira Range, Serra do Mar alkaline province: Crustal assimilation processes and mantle source signatures
ABSTRACT: Three series of alkaline dikes are characterized in a restricted area of the Mantiqueira Range: a weakly silica-undersaturated series (normative ne < 7), of potassic character, represented by basanite, tephrites, alkali basalts, basaltic trachyandesites, phonotephrites, tephriphonolites, and trachyandesites, an intermediate series (7 > normative ne

5. The Mato Perso Conduit System: evidence of silicic magma transport in the southern portion of the Paraná-Etendeka LIP, Brazil
ABSTRACT: The Mato Perso Conduit System is described from a ~ 120 km2 area in south Brazil exposing silicic volcanics of the Paraná-Etendeka LIP. A volcanic succession is defined by basaltic flows covered by flat-lying oxidized vitrophyres, banded vitrophyres cutting the lower lavas and grey flat-lying vitrophyres covering all the units. Flow morphologies d

6. Acumulação e capacidade de recuperação de metais pesados em lagoas de mineração de areia do Rio Otamiri em Owerri, Nigéria
Níveis, índice de acumulação e recuperação da capacidade de metais pesados (Pb, Cd, Cu, Ni, Zn, Fe, Mn) em lagoas de mineração de areia do Rio Otamiri em Owerri, Nigéria, foram investigados durante a estação chuvosa de 2012. Amostras de água (WC) e de sedimentos (SD) foram coletadas em seis pontos de amostragem, sendo os pontos WC 1 - WC 3 e SD 1

7. CaracterizaÃÃo tecnolÃgica e radiomÃtrica de um diabÃsio da regiÃo de ApuiarÃs - CE / Technological characterization and radiometric a region of diabase ApuiarÃs - CE
This paper presents the technological and mineralogical characteristics of a diabase, which outcrop in the form of dike is located in the district CanafÃstula in ApuiarÃs - CE. In order to assess their qualities for application as ornamental, were carried out technological tests of fitness levels and physical-mechanical, based on standards from ABNT, as we

8. Citogenética de espécies de siluriformes da região de transposição do Rio Piumhi (MG)
At the beginnig of the 60 was concluded the building of the Furnas dam over the Rio Grande, wich belongs to Parana river watershed. When the gates of the hydroelectric were closed, a dike was built to contain the waters of the dam, in order to prevent the flooding of the city of Capitólio MG. However, this dike has dammed the river Piumhi, which, at that ti

10. Arthropod succession on pig carcasses in southeastern Nigeria
O porco branco (Sus scrofa) foi usado como modelo para o estudo da sucessão de Artrópodes em cadáveres em zonas sombreadas e não sombreadas por árvores no sul da Nigéria. Nos cadáveres em decomposição em zonas sombreadas observou-se um processo de decomposição mais lento que nos expostos ao sol; 24,5 e 16,5 dias, respectivamente. Foram observadas

11. SENSORIAMENTO REMOTO APLICADO AO ESTUDO DO COMPORTAMENTO ESPECTRAL DA ÁGUA NO RESERVATÓRIO PASSO REAL RS / REMOTE SENSING APPLIED TO THE STUDY ON WATER SPECTRAL BEHAVIOR IN PASSO REAL RS RESERVOIR
The building of reservoirs for energy generation and water flow control generated river environmental changes as well as modifications on fluvial environment. In such context, remote sensing is a tool that enables spatial analysis and temporal aquatic environmental information acquisition. This research present a study on water spectral behavior in Passo Rea
