Caracterização geoquímica de solos e área de influência dos Carbonatitos Picada dos Tocos e Passo Feio, Caçapava do Sul - RS

Abstract

Mining is indeed of the largest contributors to the development of humanity. Without its presence, we definitely would not have evolved as much as humanity. Currently, carbonatites are several prospective studies due to their high chance of containing calcium carbonate, magnesium and iron, and are also considered extremely rich in phosphate and minerals rich in Rare Earth Elements (ETR). Phosphates are currently being studied for their excellent soil correctives and ETRs for their use in the development of cutting-edge technology. In this context, the municipality of Caçapava do Sul has two occurrences of carbonatites, Carbonatito Picada de Tocos and Carbonatito Passo Feio. In order to enrich knowledge and assist in carbonate prospecting, this work aimed to characterize the soil geochemistry as occurrences of carbonatites in Caçapava do Sul. The soil where analyzed with Inductive Dispersion X-ray Fluorescence Spectrometry. The data obtained revealed that there is an anomalous presence of Ca, Mg, Fe, Ti, P, Mn, Co, Th and Ce elements. This anomaly is directly linked to the presence of carbonatites in the region and their chemical composition. The Carbonatito Picada dos Tocos has an area of influence to the northeast, while Carbonatito Passo Feio has an area of influence to the south.
