Química Mineral de Granada no Estudo da Proveniência Sedimentar do Litoral Norte do Estado do Rio de Janeiro, Brasil

Abstract: ResumoA determinação da composição química da granada, aliada à identificação da assembleia de minerais pesados, representa uma importante ferramenta para a determinação de fontes de sedimentos com maior precisão. Neste trabalho, o segmento litorâneo do norte do estado do Rio de Janeiro, limitado pelas desembocaduras dos rios Paraíba do Sul e Itabapoana, teve sua proveniência sedimentar estudada por meio da análise da composição química de grãos de granada em MEV-EDS, integrada à identificação da assembleia de… Show more

“…Moreover, according to the Köppen classification, the study region climate is subtropical with hot summers, without prolonged droughts, and average rainfall distributed throughout the year (SEMA, 2012;SILVA et al, 2019), thus favoring the weathering processes. The scores associated with RE 1 and RE 2 elementary ratios allow identifying the source rock composition (SANG et al, 2018;SOUSA et al, 2018).…”

“…https://doi.org/10.1590/S1413-415220220230 Understanding the mobility of major oxides during the weathering processes has been proposed as an alternative to identify sediment formation zones (GOMES; ALMEIDA; SPERANDIO, 2018;SANG et al, 2018;SILVA et al, 2019;SOUSA et al, 2018). Additionally, sediment quality is often assessed by environmental geochemical indices based on average concentrations of local inorganic chemical compounds, the background values, compared to bottom levels as a tool for water resource management (BILLAH; KOKUSHI; UNO, 2019;MIZAEL et al, 2020).…”
