Mapeamento geológico 1:50.000 da Chapada dos Guimarães (MT) – Área 2

Abstract

This is the graduation thesis for the Geology degree at the Federal University of Goiás. The study presents the results of geological mapping in the region of Chapada dos Guimarães National Park. Located in the municipality of Chapada dos Guimarães, Mato Grosso, the park covers approximately 45.2 km² and comprises lithostratigraphic units ranging from the Neoproterozoic to the Mesozoic. The main objectives were to produce geological mapping at a 1:50,000 scale and to characterize the lithological and structural units. The methodology included literature review, satellite image interpretation and DEM analysis, description of outcrops, sampling and collection of structural data in the field, and, finally, microscopic analyses, report preparation, and development of thematic maps. The results show that the sedimentary formations of the Paraná Basin were deposited in erosional contact over the metasedimentary rocks of the Cuiabá Group. Photo-structural analysis revealed strong geomorphological lineaments that correspond to the fracture patterns observed in the field. Structural interpretations indicate that the bedding of the Paraná Basin units and the structures present in the Cuiabá Group display fracture patterns that reflect regional tectonic controls. This report consolidates the geological interpretation of the area by integrating field data, remote sensing, and laboratory analyses, resulting in a coherent geological model for the studied region.
