Item Caracterização dos perfis de solo derivado da fácies anortosito da suíte Córrego das Campinas, associado à ocorrência de caulim, na região de Porangatu, Trombas e Santa Tereza de Goiás, Goiás(Universidade Federal de Goiás, 2024-08-03) Maia, Débora Santos; Lima, Hugo Figueiredo de; Vieira, João Emerson Vasconcelos Leite; Reis, Mateus Andrade; Reis, Mateus Andrade; Canile, Fernanda Maciel; Arab, Paola BrunoConsidering the countless applications of clay minerals in the industry in its most diverse ramifications, the present work sought to characterize the soil profiles in the triple border of the municipalities of Trombas, Porangatu and Santa Tereza de Goiás, in the State of Goiás. In order to characterize the type of existing material, which uses and how it occurs throughout the entire study area. To this end, it was necessary to map the occurrences of rock and soil, analyze the physical, chemical and mineralogical properties of the soils and its horizons. Then it was carried out photo interpretation work looking for clear exposures of soils (clearances) and rock exposures. During the field activity, systematic sampling of variations in soil intervals and soil types was carried out, in addition to rock sampling. Sampling was done in the form of channel and spot sampling. Subsequently, geochemical analysis and geotechnical tests of the material were carried out in the laboratory. Therefore, it was verified that the existence of kaolinite, the main constituent of kaolin. The kaolin in the locality is primary, resulting from the alteration of the source rock (anorthosite) and is mainly associated with the B horizon of the soil. It is commonly noted that a superficial laterite crust, associated with alluvial deposits, contains concentrations of iron and titanium oxides in the kaolin, which interfere with the color of the material, making it possible to identify horizons of different colors such as red, yellow and white. It can be concluded that the soil profile in the study area is mostly composed of clay minerals, laterite crust and alluvial deposits. The color of the kaolin horizons is mainly due to the iron present in the laterite crust and minerals present in the anorthosite. It is necessary to process the material to remove the iron for applications in industry in general.Item Mapeamento geológico-ambiental, em escala 1:25.000, de área adjacente ao reservatório do ribeirão João Leite, região metropolitana de Goiânia - Goiás(Universidade Federal de Goiás, 2022-10-08) Álvares, Amanda Pereira; Silva, Ariele Lisita; Silva, Icaro Souza; Canile, Fernanda Maciel; Canile, Fernanda Maciel; Nogueira Neto, José de Araújo; Trindade Netto, Gil BarretoThe 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.
