This study investigated the environmental quality of Bizerte Lagoon (Tunisia) through an integrated approach that combined environmental, biogeochemical, and living benthic foraminiferal analyses. Specifically, we analyzed physicochemical parameters water sediment. The textural, mineralogical, geochemical characteristics sediment, including total organic carbon, nitrogen, simultaneously extracted metals (SEM), acid volatile sulfides (AVS), chlorophyll a, CaCO3, changes in bacterial...
Abstract This paper presents new field, petrographic, geophysical, geochemical and geochronological data for the felsic mafic magmatism of eastern Parnaíba Basin, integrating previously published with surface acquired within scope Cooperation Program developed by UERJ-Petrobras. New precise 40 Ar– 39 Ar Cambrian ages ( c. 508–506 Ma) were obtained volcanic to subvolcanic rocks associated intracontinental rift sediments in São Raimundo Nonato area SE basin. The results include detection three...
Abstract This work aims to identify the influence of climate change on sedimentary processes associated with usual regression process during rise sea level in early/middle Holocene southeastern Brazil. The studied area is eastern side Marambaia Barrier Island, which borders Sepetiba Bay (Rio de Janeiro State, SE Brazil). Nowadays, a ≈ 40 km long and 5 wide sandy ridge, shields from direct Atlantic Ocean. To achieve this goal, grain size, geochemical data (including elemental stable...
Esse trabalho apresenta os resultados de pesquisas geológicas e gravimétricas realizadas na região do Complexo Alcalino Mendanha. As técnicas aplicadas foram mapeamento geológico básico 1:50.000 gravimetria terrestre, com equipamentos LaCoste & Romberg, controle posicionamento por GPS diferencial. A análise integrada dos dados permitiu gerar seções modelos gravimétricos 2,5D, estimando a geometria da suíte alcalina em subsuperfície. O Mendanha é constituído rochas composição sienítica...
<title>Abstract</title> This study aimed to map magnetometric structures west of the city Manaus up Codajás, using data from aerial surveys and processed through Geosoft Oasis Montaj software. For processing, filtering frequency enhancement techniques were applied, resulting in maps anomalous magnetic fields, analytical signal maps, upward continuation for subsequent identification subsurface structures. After identifying these structures, efforts made interpret compare them with mapped by...
Dados aerogeofísicos do Projeto Geofísico Brasil-Canadá foram reprocessados e interpretados em conjunto com técnicas de processamento digital imagens a finalidade realizar uma prospecção regional para ouro no Grupo Paranoá. O modelo prospectivo utilizado definição alvos potenciais envolve associação das mineralizações auríferas veios quartzo sulfetados zonas hidrotermais. Os processos hidrotermais freqüentemente alteram as concentrações originais hidróxidos óxidos ferros rochas, bem como dos...
In the present work we interpret gravity data to provide a high-resolution structural framework for Sergipe Basin. We applied multiscale edge method Bouguer anomaly and defined several major subtle gravimetric lineaments within Japaratuba Low. Our results will serve as guidelines next step of ongoing work: detailed interpretation available 2-D 3-D seismic data. One goal this subsequent is search sweet- spots in unconventional shale reservoirs.

No presente trabalho ilustramos a aplicabilidade dos métodos aerogeofísicos no suporte ao moderno mapeamento geológico, em especial de rochas graníticas. Na região estudada (Nova Friburgo, Serrana do Estado Rio Janeiro) afloram maciços graníticos com assinaturas geofísicas distintas. Utilizou-se como ferramenta dados aeromagnéticos e aeroradiométricos. O mapa intensidade campo magnético total forneceu informações sobre as estruturas (falhas, diques, contatos geológicos) permitiu...
