Viabilidade da aplicação do GPR para o mapeamento de camadas de bauxita laterítica e de goethita

Abstract

The GPR electromagnetic method was tested in the mapping of layered mineral deposits, located in two different geological environments. Measurements were made with the aim of mapping layers that form the deposits of supergene origin of lateritic bauxite and goethite. The surveys for the mapping of the bauxite layers were conducted in the municipality of Paragominas, in Pará State. The measurements for mapping the goethite layers were carried out inside a private property, which is located between the towns of Xambioá and Vanderlândia, Tocantins State, near the Araguaia Belt. The study had as main objective to identify the parameters depth and thickness of the mineralized zones, which may help in the work of exploitation of the ores. The obtained results can be considered as very satisfactory, because the method presented a good response for both types of ores investigated, making possible the characterization of the layers and the verification of their depths and thicknesses.
