Modelagem geológica a partir de furos de sondagem e análise estatística de teores de K₂O aplicadas a zonas anômalas de potássio

Abstract

The present work focused on the three-dimensional geological modeling of potassium mineralized bodies in the region of Sacramento-MG, based on data from boreholes. The research was carried out based on information provided by the company K-Nutrisolo Mineração Sacramento LTDA, integrating lithological, topographic and analytical data in a digital environment through the Leapfrog Geo software. The objectives of the study were: i) to organize and structure a geological database based on the boreholes; ii) to develop a 3D geological model representing the distribution of lithological units, with emphasis on potassium mineralization; iii) to analyze the geometry and spatial distribution of the mineralized bodies; iv) evaluate the K₂O contents based on the available chemical analyses, verifying their economic viability. The final model allowed for a clear interpretation of the distribution of mineralized bodies, identification of zones with greater potential for use and support future decisions aimed at mineral prospecting. In addition to its applied value, the work also has academic relevance by demonstrating, in practice, the importance of three-dimensional geological modeling as a tool to support mineral research in initial deposit evaluation studies.
