The exploration of gold and copper is essential for the sustainable development mining worldwide in Brazil, given dependency on imports. This study aims to reassess identify promising areas sulfide prospecting southern with technologies, including radar images (ALOS PALSAR) software (PCI Geomatics CATALYST Professional Complete, version 2023, QGIS 3.38.1 (Grenoble), Spring 5.5.6, Orient 3.20.0), extraction processing tectonic lineaments. comparative analysis between these linear structures...
<title>Abstract</title> This study utilizes gamma-ray spectrometry to identify source areas of gold recognized in geo-chemical prospecting work stream sediments. The local geological context is represented by the Passo Feio Metamorphic Complex, which contains deposits possibly hosted quartz veins concordant with metamorphic foliation, composed quartzites, schists, and amphibolites. followed sequence: reconnaissance, drone survey, spectrometric acquisition. Field reconnaissance indicated an...
ABSTRACT. The assessment of contamination caused by improper disposal solid waste involves integrated analysis the physical environment, which shall range from location pollutant source, flow paths and accumulation zones. environmental diagnosis in complex aquifer systems clearly define dimensions contaminated area means technical options that allow adequate wells for quantification contents. This work presents results use Electric Resistivity Tomography (ERT) mapping leachate originated...
ABSTRACT. This paper discusses the results of combined application Electric resistivity and Induced Polarization methods into a mineral occurrence manganese supergenic origin, characterized by oxides iron with terrain to powdery texture, arising from weathering spessartite contained in metasediments.Keywords: exploration, oxide, resistivity, chargeability, 3D modeling. RESUMO. Este trabalho discute os resultados de uso combinado dos métodos da Eletrorresistividade e Polarização Induzida numa...
Abstract Population growth and social economic development demand increasing volumes of water for public supply, especially in scenarios where surface sources such as rivers may not meet the basic demands population. In southeastern Brazil, with emphasis on Piracicaba region, there is a conflict over use regarding agricultural industrial activities, sugar-alcohol sector widely highlighted. The region has thousands hectares sugarcane cultivated, which requires intensive fertilizers...
Quantitative and qualitative analyses developed with dead living testate amoebae were carried out in Lagoa do Peixe National Park, near the central portion of external coastal plain Rio Grande Sul State, south Brazil. Samples collected bottom sediments from distinct lothic lenthic environments show Difflugia oblonga, Pontigulasia compressa Cucurbitella mespiliformis as dominant species assemblages environments, last two also present assemblage. In are Hoogenraadia africana, Centropyxis...
Este trabalho apresenta uma análise comparativa entre dados de tomografia elétrica detalhe, obtidos sobre terreno granítico onde ocorre fluxo subterrâneo em sistema aquífero fraturado, adquiridos por meio dos arranjos dipolo-dipolo, Schlumberger e Wenner, na região Caçapava do Sul (RS). Dados estruturais exposições rochas 100 m 300 da área estudo serviram base para produtos geofísicos definição modelo matemático mais factível a realidade geológica. O fraturamento predominante possui...
O atendimento e manutenção de demandas industriais construção civil em relação a insumos minerais estimula pesquisas para descoberta novos depósitos ou ampliação jazidas conhecidas. método geofísico eletromagnético indutivo (EM) é muito utilizado estudos envolvendo pesquisa metálicos. Na busca por cobre o EM eficiente devido este metal se comportar como excelente corpo condutor na presença um campo magnético, que sua vez possibilita distinção dos demais constituintes rochosos pela elevada...
Landfill is an engineering work that aims at to accommodate residues in the smallest possible space soil, with minimum damages environment and public health. One constructive forms of a controlled landfill excavation ditches appropriate dimensions, for disposition solid without compactation or impermeabilization. Liquid effluents generated similar volumes residues, disposed ages different from closing, it should result physical chemical alterations you correlated time residence materials....
Groundwater reserves are strategic sources for public water supply. This regional study, accompanied by geomorphologic, geologic, and hydrostratigraphic maps, highlights the importance of stratigraphic hydrochemical research in preserving areas susceptible to contamination, such as aquifer recharge zones. The aquifers were subdivided into Pre-Guarani Aquifer System (PRE-GAS), Guarani (GAS), Serra Geral (SGAS). article paper analyzed hydrogeological characteristics Pardo River watershed,...

The local geological context is represented by the Passo Feio Metamorphic Complex, which contains deposits possibly hosted quartz veins concordant with metamorphic foliation, composed quartzites, schists, and amphibolites. followed sequence: reconnaissance, drone survey, spectro-metric acquisition. Field reconnaissance indicated an alternation rocks...
Geophysical investigation in the coastal region of emerged portion Barra Falsa, Bojuru, RS, Brazil, provided valuable information about depositional evolution and paleoenvironmental changes that occurred during Quaternary period. The combination electromagnetic surveys, analysis stratigraphic wells, 3.5 kHz reflection seismic previous geological data allowed for a comprehensive characterization sedimentary environments associated with sea-level fluctuations. Electromagnetic surveys using...
The Tramandai River and the Passo Lagoon are fluvial-lacustrine systems inserted in north of coastal plain Rio Grande do Sul State, Brazil. Bottom siliciclastic sediments revealed 71 distinct taxa testate amoebae 5.793 analyzed specimens. Pontigulasia compressa Carter, 1864, Difflugia oblonga f. tenuis Penard, 1890, Centropyxis platystoma (Penard), 1890 Cucurbitella dentata var. simplex trilobata Gauthier-Lievre Thomas, 1960 most frequent species, former three constant, as well aculeata...
The geophysical diagnosis of mineral deposits can be extremely useful in detailing mineralized zones and is a strategy for direct sampling by probing holes content analysis. This study involves the combined use Electrical methods (DC resistivity Induced Polarization), geological recognition structural field analysis, with occurrence copper, previously described systematic geochemical survey carried out Geological Survey Brazil (CPRM), located north Camaquã Basin, extreme south Brazil....
The purpose of this research is to characterize geoelectrically an occurrence dolomitic marble at the SE border Granito Caçapava do Sul in detailed scale applying geophysical resistivity method and remote sensing.In order it two dimensional profiles were made using values apparent make inversion process.The use sensing consisted application directional filters satellite images LANDSAT 5, TM orbit, recognize structural lineaments.The joint analysis these data allowed identifying features...
