Integração de dados geoquímicos na região da Sanga da Brandina, Caçapava do Sul-RS

Abstract

Geochemistry is the science that studies the chemistry of planet Earth, covering the distribution, migration, and formation of the chemical elements that constitute it. This paper compared the superficial water in the Sanga da Brandina’s region, Caçapava do Sul, with the lithology present in the region (Granite Complex Caçapava do Sul), through chemical analysis. The elements analyzes were compared with rock geochemical data to trace the similarities between the lithosphere and biosphere using statistical correlation method. The presence of water in liquid state, in contact with the bedrock, promotes chemical reactions, carrying dissolved substances along its trajectory. In this way, the water, when leaching the soils and the rocks, is enriched in mineral salts in solution, from the dissolved bedrock. The results of the analyzes show that the physicochemical characteristics of the waters and current sediments are a reflection of the percolated way. The existing amount of dissolved salts reflects the variation of the geochemical behavior that operates in the region of study.
