Abstract

Currently, carbonatites are being severally studied in a prospective matter due to their high chance of containing calcium carbonate, magnesium and iron. They are also considered extremely rich in phosphate and minerals rich in Rare Earth Elements (ETR). In this context, the municipality of Caçapava do Sul has two occurrences of carbonatites: Picada de Tocos and Passo Feio. In order to enrich knowledge and assist in carbonate prospecting, this work aimed to characterize the soil geochemistry at the occurrences of the carbonatites in Caçapava do Sul. 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.
