Trabalho de Conclusão de Curso (Graduação) - Faculdade de Ciências e Tecnologia, Universidade Federal de Goiás, Goiânia, 2021.http://repositorio.bc.ufg.br/handle/ri/20624This work was accomplished through the processing and the interpreting of images, geophysical, geochemical, and environmental data and lithological and structural data obtained in the field. The geological mapping in the Anicuns region had as result the outlining of units in the Goiás Magmatic Arc (AMG) context, including gneisses from the Sanclerlândia Metagranite and rocks from the Anicuns-Itaberaí Metavolcanosedimentary Sequence, units associated to sincollisional magmatism (Córrego da Lavrinha and Creoulos granites) and mafic rocks associated to volcanism installed through the collisional orogen collapse (Córrego Seco Complex), all comprising the Brasília Belt. Four deformational phases were recognised in the area: D1 represents an EW compression that generates folds verging East, which is refolded by D2, an EW compression from D1 progression; D3 is a NS lateral shortening that creates crenulation with an EW axis; D4 represents the ruptile last stage of the EW compression, with shear zones and thrust faults associated. The area is important in the understanding of the Brasília Belt evolution because its rocks are inserted in the tectonic and magmatic events related to the belt development, starting with the AMG formation in the Tonian Period, during the fracturing of the Rodinia Paleocontinent, and progresses until the Goiás Paleocean closure, when the last magmatic events occur. Economically, the area is interesting because of the presence of potential to numerous metallogenetic processes, including contact metamorphism, volcanism and hydrothermalism. The main mineral occurrences are gold and gravel.porAcesso AbertoMapeamentoMappingArco magmático de GoiásGoiás magmatic arcComplexo córrego secoCórrego seco complexTCC
