The structure affects rocks of the Monte Carmelo Complex, Abadia dos Dourados Complex, and Araxá Group, constituting a structurally significant feature within the southern portion of the Brasília Belt. A multiscale approach was employed based on the integration of morphostructural, airborne geophysical, field geological, microstructural, and three-dimensional geological modeling data. The analysis of Digital Elevation Models (DEM), combined with the interpretation of gamma-ray spectrometric and magnetic data, revealed a strong NW–SE structural control over the relief and drainage network, evidenced by rectilinear channel segments and fluvial deflection anomalies. Geophysical products revealed radiometric and magnetic contrasts associated with the different geological units, indicating that the granitic bodies acted as relatively more competent domains during regional deformation, promoting strain partitioning along their margins. Three-dimensional geological modeling demonstrated the spatial continuity of these structures at depth and enabled the correlation between geophysical domains and surface observations. Petrographic and microstructural analyses identified intracrystalline deformation features and dynamic recrystallization in quartz, associated with the predominantly brittle behavior of feldspars, indicating deformation under low-grade greenschist facies metamorphic conditions. Furthermore, the observed mineral assemblage suggests that the structure acted as a conduit for the circulation of fluids. Although no diagnostic kinematic indicators were identified to unequivocally determine the sense of movement of the structure, the integration of the different datasets allowed the characterization of the spatial distribution of deformation and the role played by the Douradinho Shear Zone in the lithostructural arrangement of the local geological units. The results contribute to the understanding of the structural evolution of the southern portion of the Brasília Belt and provide a basis for future tectonic and geophysical investigations in the region.

These lithologies are inserted in the southern sector of the Brasília Fold Belt and are related to a syn-tectonic event responsible for the intrusion of granitoids along regional foliations and shear zones developed within the schists. The Douradoquara Granite is located west of the municipality of Douradoquara, Minas Gerais, and was previously mapped by CODEMIG (Catalão Sheet – SE.23-Y-A-I, 2017) at a 1:100,000 scale. The present study aimed to map this granitic body at a 1:30,000 scale, seeking a higher level of detail, as well as the individualization and characterization of its facies based on textural, compositional, and structural variations. The applied methodology was divided into three stages. The pre-field stage consisted of bibliographic review, satellite image analysis, interpretation and processing of aerogeophysical image data, and interpretation of structural lineaments, allowing the preliminary delimitation of zones with similar geomorphological and structural characteristics. The field stage involved geological mapping of the outcropping lithotypes, distinguished based on textural, mineralogical, and structural criteria, in addition to photographic documentation and sample collection. Finally, the post-field stage comprised macroscopic and microscopic analyses of the samples, enabling their classification and differentiation into facies, culminating in the elaboration of a new geological map with redefined limits of the granitic body. The results indicate that the area corresponding to the Douradoquara Granite unit is smaller than that presented in the regional 1:100,000-scale mapping by CODEMIG, with a greater predominance of metasedimentary and metamafic host rocks of the Araxá Group, mainly represented by garnet-bearing quartz–muscovite–biotite schist and amphibolites occurring as lenses with a NW–SE trend. The granitoids are foliated, with preferential orientation according to the regional NW–SE trend. The essential mineralogy consists of quartz, microcline, oligoclase, biotite, muscovite, and garnet, allowing the classification of the lithotypes as inequigranular monzogranites to granodiorites. Based on differences in color and mineralogical composition, the body was subdivided into two facies: inequigranular gray facies and inequigranular whitishgray facies, with their main distinction related to the presence of primary muscovite in the inequigranular whitish-gray facies. The presence of aluminous minerals, such as garnet and primary muscovite, indicates that the Douradoquara Granite resulted from crustal melting, characterizing it as a peraluminous S-type granite. The occurrence of quartz-feldspathic pockets within the foliation of garnet-bearing quartz–biotite–muscovite schist and the magmatic foliation with a regional NW–SE trend evidence its syn-tectonic emplacement, strongly controlled by the structural framework of the host rocks, reflecting the exploitation of these structures during intrusion, as well as the deformational processes active during the Neoproterozoic evolution of the Brasília Fold Belt Wed, 18 Mar 2026 00:00:00 GMT https://repositorio.ufu.br/handle/123456789/49623 2026-03-18T00:00:00Z https://repositorio.ufu.br/handle/123456789/49574 Title: Coleta seletiva em Uberlândia (MG) sob a ótica da Psicologia Ambiental: perspectivas para o fortalecimento da gestão integrada dos resíduos sólidos Abstract: The generation of solid waste has become an increasingly complex and urgent issue. Population growth, coupled with the intensification of economic activity, has increased waste generation, often without the infrastructure required for its proper disposal. The presence of waste in space is not limited to a technical management problem but reflects deeper fractures in the relationship between society and nature, compromising environmental quality, the aesthetics of the landscape, and the symbolic bond between individuals and place. In this context, selective collection constitutes a central component of Integrated Solid Waste Management, although its effectiveness cannot be explained solely by the existence of infrastructure, regulations, or informational campaigns. In the municipality of Uberlândia, Minas Gerais, despite the expansion of the service's territorial coverage, public adherence remains limited, as evidenced by the continued disposal of recyclable waste through conventional waste collection and sanitary landfilling. Based on this observation, the primary objective of this doctoral thesis is to understand the factors that influence public adherence to selective collection in the municipality of Uberlândia in 2024. The research demonstrates that adherence to selective collection is not primarily the result of isolated individual decisions but rather the expression of a person–environment relational system, in which spatial, institutional, educational, and psychological dimensions shape pro-environmental behavior. The methodological procedures included bibliographic, documentary, and field research, using institutional data and statistical information. Thematic maps were produced based on secondary data obtained from official sources using QGIS software, focusing on variables such as service coverage, population density, and waste collection infrastructure. In addition, intensive direct observations and exploratory semi-structured interviews were conducted through a questionnaire with 34 participants selected for their representativeness in the municipal selective collection process from a population of 166 workers involved in the program. The findings reveal a mismatch between the available infrastructure and its effective appropriation by citizens, indicating that low adherence to the service is not primarily explained by a lack of knowledge or information. The strengthening of Environmental Education, by incorporating psychological dimensions related to perception, values, beliefs, norms, attitudes, cognition, and cognitive heuristics, proved to be decisive in shaping pro environmental behavior, thereby promoting greater public adherence to selective collection. Furthermore, factors associated with accessibility, visibility, environmental setting, and other environmental attributes of the service infrastructure, when designed to account for the environmental stimuli that shape individual behavior, also tend to increase the likelihood of public adherence. Therefore, public adherence to selective collection depends on the articulation between the structural conditions of space and the psychological processes associated with person–environment interaction. Accordingly, increasing adherence to selective collection requires strategies that integrate Environmental Education, the reorganization of spatial and institutional contexts, and interventions grounded in the principles of Environmental Psychology. By highlighting the centrality of the person environment relationship in solid waste management, this thesis contributes to advancing discussions on public policies and to building more consistent pathways toward the transformation of mindset.
