GEOQUÍMICA DE ELEMENTOS MAIORES EM SEDIMENTOS DE BARRAGENS DOMINICANAS: ANÁLISE DA SUA PROVENIÊNCIA

Abstract

The climatic conditions of Dominican Republic are conducive to the existence of high erosion rates, which may represent high sedimentation rates, that can make the dams silted. It is intended to do a geochemical characterization of the dam’s sediments, in order to study the sedimentary processes of the drainage basins. Through the analysis of the sediments of the bottom of two dam reservoirs (Tavera and Sabana Yegua) and the soils from the drainage basins, we intend to make a comparative geochemical analysis to identify the main sources of the sedimentary material of each dam. This study corresponds to a preliminary approach, which consists of the analysis of major elements by ICP-OES, in an attempt of identifying the sediments provenance.
