Resumo
The study in question deals with the technological characterization and mineral chemistry of a mylonite located in the municipality of Araguaçu, situated in the Western mesoregion, southern region of the State of Tocantins, and the Rio Formoso microregion, bordering the State of Goiás. Geologically, this area is part of the north-central portion of the Tocantins structural province, at the still poorly defined boundary of the Brasília and Araguaia orogens. The main objective of the work was to carry out lithostructural mapping of the area, characterize the mineral chemistry, and assess the potential of mylonitic rocks occurring in the Araguaçu-TO region for use as ornamental stone. The aim was to evaluate their technological parameters, in accordance with the standards of ABNT, ASTM, and Frazão and Farjallat, to indicate this material for applications in the ornamental stone market. In recent years, there has been a significant increase in demand for ornamental stones, driven by the growth of the construction industry and tourism, which has put great pressure on deposits and increased the need for sustainable management of natural resources and the search for alternative production methods. In the study area, four lithotypes were mapped from the base to the top: I - Baixo Araguaia Group, specifically the Xambioá Formation; II - Água Bonita Formation; III - Mylonite, the subject of this study; and IV - Detrital-lateritic covers, showing a predominantly NE-SW structure. The study provides a geological base at a scale of 1:30,000. The results suggest that the mylonite is suitable for various applications in the construction industry, such as floor and wall coverings, countertops and sinks, facades and exterior cladding, staircases, among others.
