Resumo
The area under study comprises a peri-urban strip, located in the northwest region of the municipality of Goiânia, capital of the state of Goiás, which is part of the rural macro-zone of João Leite, an area destined for the preservation and sustainable use of its resources, under the influence of the Área de Preservação Permanente de João Leite (APAJoL). It is inserted in the geological context of the Anápolis-Itauçu Complex, belonging to the Brasília Belt, formed during the Brasiliana Orogeny in the Neoproterozoic. The objective of this work was to carry out an integrated mapping, in which the main aspects of the physical environment are related to geoenvironmental characteristics, based on the analysis of variables such as hypsometry, slope, drainage density, soil use and occupation, erosive susceptibilit, structural surveys, among others. Furthermore, in the area, four lithotypes belonging to the Anápolis-Itauçu Complex were characterized: i) garnet-hornblende-clinopyroxene-plagioclase granulite; ii) hypersthene gneiss, with presence of hornblende; iii) tremolithites, indicative of metasomatism; vi) quartzite metasedimentary sequence. The results obtained suggest that it is necessary to adopt inspection measures and control the advance of areas for agricultural purposes, implementation of allotments and residential condominiums that increase the deforestation of the Cerrado and cause erosion that cause silting and pollution of the rivers that supply the city.
