Abstract

Several geoscientific researches rely on a robust elemental and geochemical characterization, with application spanning water quality assessment, evolution of sedimentary basins and igneous and metamorphic petrology. The portable X-ray fluorescence spectrometer is a non-destructive technique and will be used to analyze rocks, soils and sediments. The equipment will be used for initial geochemical investigations as well as in projects that require the acquisition of a high volume of data. The objective to be achieved with the requested equipment is to meet the needs of the associated projects listed in the proposal, as well as to serve small, medium and large projects with partner institutions. The Department of Geology and associated centers such as UNESPetro have a broad research program, requiring fast, precise and accurate analytical techniques that cover the determination of major and trace elements. Advanced analytical techniques, such as high-resolution mass spectrometry already installed at the Host Institution, require complex sample preparation processes and specialized operators, which increases the cost of these analyses. Thus, the geochemical pre-characterization that can be achieved with a portable FRX make the analysis on the advanced techniques more efficient, mitigating possible risks for these more robust analyzes and ensuring better results.
