Artigo IPEN-doc 27904 Performance of the X-ray powder diffraction (XRD), X-ray fluorescence (XRF) and the industrial computed tomography used for characterization of the vesicular volcanic rock2021 - SANTOS, R.S.; CAVALLARO, F.A.; BERNARDES, T.L.S.; AMADEU, R.A.; GARCIA, R.H.L.; VELO, A.F.; MESQUITA, C.H.; HAMADA, M.M.Volcanic rock is a designation in geology given to extrusive igneous rocks. One type of igneous rock of interest, in economic terms, is vesicular, since, besides the knowledge of the morphology (positioning, size, direction, and interconnectivity of the vesicles) of these structures within the spill, there is also an economic interest regarding the possibility of this rock as a reservoir of fluids (water and hydrocarbons). In this work, samples of vesicular volcanic rock from the Paraná Basin were studied for their characterization, aiming to contribute to the knowledge of this rock proprieties as a reservoir of fluids. The elements present inside the rocks were identified and quantified by X ray fluorescence and X ray diffraction. The dimensions of the vesicles and the interconnection between them could be clearly observed in the reconstructed images of the rocks measured by the third generation Gamma ray industrial tomography techniqueArtigo IPEN-doc 27895 Petrological study of the Iraty Formation Shale Rocks from Paraná Basin, Limeira, São Paulo2021 - BERNARDES, T.L.S.; AMADEU, R.A.; SANTOS, R.S.; GARCIA, R.H.L.; VELO, A.F.; CAVALLARO, F.A.; MESQUITA, C.H.; HAMADA, M.M.Shales are fine-grained rocks formed by clays and silt-sized particles in thin, relatively impermeable layers. They are originated from rocks that suffered weathering and erosion and their composition is quite variable. When oil production declines, interest arises to improve the understanding of the physicochemical properties of unconventional rocks, like shale. For the characterization of the shale samples of the Iraty Formation, the gamma-ray computed industrial tomography technique has been proposed to be used as an alternative to obtaining information about each element present in the mineral, the pore distribution, through the shale morphology. The tomographic results were compared with those obtained by conventional methodologies used in the petrological analysis, such as scanning electron microscopy (SEM), x-ray fluorescence, and x-ray diffraction.Resumo IPEN-doc 22255 Caracterização do sistema tomográfico computadorizado industrial para raios gama2008 - PEREIRA, JOAO C.S. de M.; MESQUITA, CARLOS H.; HAMADA, MARGARIDA M.Resumo IPEN-doc 22121 Caracterização do sistema tomográfico computadorizado industrial para raios gama2007 - PEREIRA, JOAO C.S. de M.; MESQUITA, CARLOS H.; HAMADA, MARGARIDA M.Resumo IPEN-doc 08545 Plastic scintillator detection efficiency for beta and gamma radiations in function of the detector thickness2002 - MADI FILHO, T.; MESQUITA, C.H.Resumo IPEN-doc 07803 Estudo de dano da radiacao nos detectores plasticos cintiladores1998 - HAMADA, M.M.; RELA, P.R.; COSTA, F.E.; MESQUITA, C.H.Artigo IPEN-doc 09405 Analise do dano de radiacao gama em detectores organicos contendo PPO2002 - FERNANDES NETO, J.M.; MESQUITA, C.H.; DUARTE, C.L.; HAMADA, M.M.
