Resumo
The present work consists of a detailed geological mapping study in the region of the headwaters of the Vermelho River and adjacent areas in the municipality of Goiás (GO), carried out at a scale of 1:20,000. The main objective of the study was to analyze and describe the geological characteristics of the region, aiming to understand its geological and structural evolution. The adopted methodology involved fieldwork, analysis of collected data, such as direct observations of rocks and geological structures, as well as the collection of samples for petrographic and geochemical analysis. Additionally, geophysical data and topographical survey information were used to assist in the interpretation of geological features. Fourteen lithological units and alluvial cover were identified. These units were placed in the context of existing literature. Petrographic analyses allowed the characterization of rocks in terms of mineralogy and texture, contributing to the interpretation of formation and metamorphic conditions. Geochemical analyses aided in understanding the chemical characteristics of the rocks, providing insights into the provenance of the rocks and associated geological processes. This geological mapping study provides important insights into the geology of the study area, such as the relationships between the mafic-ultramafic rocks of the Goiás Velho Group and the Caiçara Complex, and between these rocks and the Serra Dourada Group. The findings are relevant not only for understanding the local geological evolution but also for comprehending geological phenomena in broader contexts. Furthermore, the mapping serves as instrumental material for Ediminas Mineração Ltda, providing support in the context of their mineral exploration activities.
