    (Universidade Federal de Goiás, 2023-09-22) Oliveira, Fernando Soares Ribeiro de; Guerrero, Cintia Isabel de Campos Roque; Andrade, Carlos Eduardo Sanches de; Andrade, Carlos Eduardo Sanches de; Souza, Alessandro de Santana Moreira de
    The continuous growth of cities entails the demand for the use of means of transport, both for passengers and cargo. In the last mile, conventional means of transport are used, which consume fossil fuels, but more and more people are looking for other transport alternatives that live better with the environment. An example is the transport by bicycles and cargo tricycles, which can be used as sustainable alternatives for transporting cargo in the last mile. This work aimed to apply a Systematic Literature Review on using these vehicles in the last mile to evaluate the environmental gain obtained. The PRISMA methodology was used, and it led to quantitative and qualitative results relevant to the theme. Ten published articles were selected, seeking to obtain the state of the art of these sustainable transport alternatives worldwide. The results showed that the use of bicycles and tricycles is successfully applied to small and medium-sized goods, food products, pharmaceuticals, and documents, among others, and has significantly contributed to the reduction of congestion, CO2, traffic accidents, and local pollutants, increasing the quality of life in cities. An analysis of the results and its application in Brazil was carried out, where the potential for use was found, but in need of improvements in cycle paths and implementation of pilot projects.

    Mapeamento geológico da região das nascentes do Rio Vermelho e arredores no município de Goiás (GO) em escala 1:20.000
    (Universidade Federal de Goiás, 2023-08-29) Gomes, Camila de Sousa; Altoé, Elisandro Seraco; Macedo, Sarah Karoline Costa; Rodrigues, Sérgio Wilians de Oliveira; Rodrigues, Sérgio Wilians de Oliveira; Lima, Martha Noélia; Carneiro, Jônatas de Sales Macedo
    The present work consists of a detailed geological mapping study in the region of the headwaters of the Vermelho River and adjacent areas in the municipality of Goiás (GO), carried out at a scale of 1:20,000. The main objective of the study was to analyze and describe the geological characteristics of the region, aiming to understand its geological and structural evolution. The adopted methodology involved fieldwork, analysis of collected data, such as direct observations of rocks and geological structures, as well as the collection of samples for petrographic and geochemical analysis. Additionally, geophysical data and topographical survey information were used to assist in the interpretation of geological features. Fourteen lithological units and alluvial cover were identified. These units were placed in the context of existing literature. Petrographic analyses allowed the characterization of rocks in terms of mineralogy and texture, contributing to the interpretation of formation and metamorphic conditions. Geochemical analyses aided in understanding the chemical characteristics of the rocks, providing insights into the provenance of the rocks and associated geological processes. This geological mapping study provides important insights into the geology of the study area, such as the relationships between the mafic-ultramafic rocks of the Goiás Velho Group and the Caiçara Complex, and between these rocks and the Serra Dourada Group. The findings are relevant not only for understanding the local geological evolution but also for comprehending geological phenomena in broader contexts. Furthermore, the mapping serves as instrumental material for Ediminas Mineração Ltda, providing support in the context of their mineral exploration activities.

    Modelo de acidente de aeronaves por colisão com aves na aviação comercial
    (Universidade Federal de Goiás, 2023-09-22) Azevedo, Bruna Borges; Bandeira, Michelle Carvalho Galvão da Silva Pinto; Bandeira, Michelle Carvalho Galvão da Silva Pinto; Roriz Junior, Marcos Paulino; Pereira, Leonardo Marini
    One of the types of occurrences that have been a problem since the beginning for aviation is bird strikes, which can generate from minor incidents to significant accidents, especially in terms of operating costs for airlines. It is observed in the literature and in the database of official entities, that the occurrence of accidents and incidents increase with the flight movement and aircraft fleet. This shows that studies in this area should be prioritized and bring more assertive responses. Thereby knowledge about what the main factors, how they relate to each other and what most impact this type of accident, collaborates with the operational safety of air transport. In this context, this work aims to present a bird strike accident model for commercial aviation that is able to quantify the impact of the main factors (time, cloud cover, species behavior, species mass, phase of flight, AGL height, affected part of the aircraft), the interrelation of these factors and their probabilities. Thus, a survey of the main factors and occurrences in Brazil between 2011 and 2021 was conducted. From the analysis, the "Bird Strike Accident Model" was proposed, developed using the Bayesian Networks method. Through graphic representation of the model, the impact of the global - among the states that make up the selected factors - was determined in scenarios with and without evidence. Comparing the scenarios with evidence and without evidence of the event, it was identified that the critical scenario in Brazil involves the following factors: fuselage as the main part reached (1º); landing phase as the most critical (2º); aircraft speed up to 80 knots (3º); engine as second main part reached (4º); height AGL up to 500 feet (5º); radome as third main part reached (6º); one bird (7º), mass up to 1,500 grams (8º); night time (9º), clear sky (10º). These results are relevant to the players involved and can contribute to the decision-making process of risk management and operational costs management of airport operators, companies, public and private entities that are related to accident investigations, regulation of civil aviation, training centers, among others.

    Mapeamento geológico-geotécnico: mina de Barro Alto - GO, Anglo American
    (Universidade Federal de Goiás, 2022-10-14) Santos, Lavoisier Matias dos; Arab, Paola Bruno; Rodrigues, Sérgio Wilians de Oliveira; Rodrigues, Sérgio Wilians de Oliveira; Temporim, Filipe Altoé; Lima, Martha Noélia
    The Barro Alto Mafic-Ultramafic Complex is part of the Goiás Massif, which is inserted in the geological context of the Tocantins Province. The deformations associated to the amalgamation of Gondwana generated in the study area a series of structures and deformation stages. A schistose (S1) subparallel to the compositional banding (S0) is characterized. Boomerang-like refolding patterns associated with flexural slip mechanisms are also observed. Conjunctively, a NE-SW and NW-SE fracture system compatible with idealized fracturing models associated with cylindrical flexural folding are observed. The Barro Alto supergene nickel deposit is composed of lithological units derived from ultrabasic rocks - dunite-serpentinized, dunite boulder, base ore, acid ore, ferruginous ore, internal waste rock, soft chalcedony, hard chalcedony and laterite soil. Nickel extraction in Barro Alto is characterized by open pit mining, which consists of excavation of the soil or soft rock and consequent modification of the topography. These modifications must be technically planned, in order to optimize resources and increase safety levels. Saprolitized heterogeneous massifs are composed of reliquary structural features, rock blocks immersed in the weathered profile (bedrock), and irregular zones with contrasting weathering. These heterogeneities usually control the failure mechanisms and locations, as well as the factor of safety. For this work, in addition to good internal practices, the geological-geotechnical characterization was carried out based on the recommendations suggested by the ISRM and the criteria established by the RMR rock mass classification system (Bieniawski, 1989). The geological-geotechnical characterization indicated a rather heterogeneous and anisotropic massif. Furthermore, the simple kinematic analysis performed as a preliminary study obtained indices higher than 0.1 (10%) for planar and wedge type ruptures.

    Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 3
    (Universidade Federal de Goiás, 2023-02-14) Silva, Gabriela Soares Freitas e; Silva, Michele Urbano da; Reis, Mateus Andrade; Reis, Mateus Andrade; Heringer, Rodrigo de Almeida; Lima, Martha Noélia
    The area of study is located in the southeast portion of the state of Goiás, next to the municipalities of Nazário and Anicuns. It is geologically located in the context of the Goiás Magmatic Arc (AMG), which is composed by rocks that register the complex metamorphic and structural geotectonic development, associated with the Brasiliano orogenesis (Arquean-Neoproterozoic), developed mainly during the structuring of the Brasília Belt. The integrated geological mapping aimed to map the different lithofacies associated with the outcropping units, namely: Anicuns Itaberaí Metavolcanosedimentary Sequence, Anápolis Itauçu Granulitic Complex, Campestre Gneiss Migmatitic Complex, Anicuns-Santa Bárbara Suite, Creole Granite and undifferentiated granitic intrusions. The work was carried out from the processing and interpretation of photointerpretive, geophysical, geochemical and geoenvironmental data, as well as lithological and structural data collected in the fieldwork, generating geological, structural and point maps as final products. The rocks exhibit metamorphism from greenschist facies to the amphibolite-granulite transition. Four deformational phases were identified: D1 generated a main E-W compression, marked by isoclinal folds with NS axes, which folded S0 and originated the S1 foliation; D2 represents the continuity of compression, generating parasitic folds and S2 foliation; D3 represents the formation of NW-SE shear zones and thrust faults, associated with the continuity of E-W compression; D4 reflects the decrease in compression, generating S3 foliation. The area presents occurrences of minerals used in civil engineering and industry.

    This work begins through the processing and interpretation of image data, geophysical, geochemical, mineral resources and environmental data and following data collect of lithological, structural, environmental and mineral occurrence in field. The geological mapping in the Serra da Jiboia (GO) region intend to describe and interpretate the units Anicuns-Itaberaí Sequence, Gnaíssico-Migmatítico Complex and Santa Bárbara Body. The first fase of deformation is associated to the S1 foliation, to the intrafolial folds and quartz veins, the phase 2 is characterized for the shale which is well preserved in all area and associate with the assimetric isoclinal regional fold of the Serra da Jiboia. The third phase also receive emphasis by the extensive shear zone which occurs in the Santa Bárbara Body limits, this compressive deformational fase also occurs crossing folds. The fase 4 distinguishes for the crenulations and spaced cleavage. The potential economy of the area is diverse and with emphasis on clay and gravel occurrences.

    Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 1
    (Universidade Federal de Goiás, 2023-02-15) Coutinho, Nathália Amaral; Maciel, Victor Augusto Silva; Nascimento, Estela Leal Chagas do; Lopes, Débora Nogueira; Lopes, Débora Nogueira; Santos, Marcelo Henrique Leão; Siepierski, Lincoln
    This paper presents the results obtained from the 1:50000 mapping of the Serra da Jiboia region. The detailing of the geological units was possible with the conciliation of bibliographical survey, photointerpretation, geophysical, geochemical, and geoenvironmental, lithological and structural data obtained in the field. As a result, the following mapped units were detailed in the context of the Brasília Belt brim and the Goiás Magmatic Arc (AMG): Anicuns-Itaberaí Metavolcanosedimentary Sequence (SAI), Campestre Gnaissic-Migmatitic Complex, Santa Bárbara Complex and the Creoulos Granodiorite. The SAI is characterized in forearc basin associated with an island arc system, recorded by platform sedimentation in the rhythmic-carbonate unit and marine regression depositional in the psamo-pelitic unit. The Creoulos granodiorite records syncolonal magmatism of meta to peraluminous granites. The geological evolution is marked in the Brasiliano, responsible for the opening of the Goiás Ocean and later the closure. This phase concludes the formation of island arcs and the Brasília orogen. The deformation of the rocks is represented by east-west compression that resulted in isoclinal thrust folds with N-S axis and eastward vergence with higher temperature and pressures. Conjugate fracture systems occur, with E-W and NE-SW direction that, by progressive deformation, originate NS, NW and NE transcurrent shear zones. The observed metamorphism of the rocks is a variation of high greenish schist to amphibolite facies, associated to SAI, besides hydrothermal metamorphism linked to shear zones. The area presents some economic aspects, with potential for manganese, calcitic marble and remineralizers for agriculture and gravel and sand for civil construction.

    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 Barreto
    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.

    The present work had as objective the geological mapping in the region of Nazário - GO from the accomplishment of systematic works that integrated data from remote sensing (orbital images), geophysical, geochemical, lithological, petrographic, structural and geoenvironmental surveys. The result of the integrated work was the geological cartography of Neoproterozoic units associated to the Goiás Magmatic Arc: Metavolcanosedimentary Anicuns-Itaberaí Sequence, Anápolis-Itauçu Complex, Creoulos Granite and Santa Bárbara Anorthositic Complex. Four deformational stages were recognized in the area: D1 represents E-W compression associated with regional folds with eastward vergence; D2 is the E-W compression refolding of the D1 progression; D3 characterizes shallower crustal level change during deformation progression and generates N-S lateral shortening of the D2 deformation and N-S axis crenulations; D4 represents the ruptile-ductile stage of E-W compression with formation of shear zones and thrust faults. In general, the rocks of the Anicuns-Itaberaí Metavolcanosedimentary Sequence in the study area are metamorphosed between green schist and amphibolite facies with retrometamorphism to green schist facies. The region is relevant for understanding the evolution of the Brasília Belt, as the rocks are linked to tectonic and magmatic events that started with in the formation of the Magmatic Arco f Goias. The study area is economically interesting due to the presence of mineral occurrences with potential for metallurgy (manganese and iron) and civil construction (sand, gravel, crushed stone and ornamental rocks).

    This 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.

    The 1:50.000 scale geological survey of the Anicuns region (GO) consisted in mapping an area of 128 km2, inserted in the domain of the inner zone of the Brasília Belt. In terms of mapped units, the area is constituted by metabasic-ultrabasic and metasedimentary psamo-pelitic rocks of Anicuns-Itaberaí Metavulcanosedimentary Sequence overlapped on ortho- and paraderived gneiss rocks of Anápolis-Itauçu Complex. This entire set is intruded by syn-tectonic granitic rocks of Lage Granite and Córrego Santa Rosa Metadiorite. Basic dykes related to 125º azimuth and alluvial sediments complete the local stratigraphy. In structural terms, the area contains five deformational phases related to the Brasiliano Event (the first indicated by intrafolial folds): the second formed nappes with an eastward vergence (Sn and Sn+1 foliations), the third formed interference patterns due to the change in regional stress (Sn+2 foliation) and the fourth and fifth formed transcurrent faults and sinister shear zones (Sn+3 foliation). The metamorphism of the rocks of Anicuns Itaberaí Metavulcanosedimentary Sequence varies from greenschist facies to amphibolite facies. In the Anápolis-Itauçu Complex, the metamorphism reaches amphibolite facies conditions higher than the amphibolite/granulite facies transition. The tectonic compartmentation of mapping area is marked by lateral placement of rocks of different crustal levels, but which were submitted to the same phases of regional deformation, related to compressional processes with an eastward trend. The contacts between the mapped units were defined based on the tectono-stratigraphic relationships observed in the field, complementing them with information extracted from the photointerpretation and geophysical maps.

    The detailing of the geology of the Anicuns region was made from a bibliographic survey combined with the processing and interpretation of photointerpretative, geophysical, geochemical, geoenvironmental and lithological and structural data collected in the field. The mapping made it possible to identify the lithotypes and group them into 10 lithostratigraphic units related to the Anicuns-Itaberaí Metavulcanosedimentary Sequence, Sanclerlândia Metagranite, Anápolis-Itauçu Granulitic Complex, Lage Granite, Córrego Santa Rosa Diorite, Taquaral-Trindade Suite and Cretaceous Dikes. Through the structural analysis, 3 deformational phases were identified, where D1 resulted in the main E-W shortening, pronounced in a set of regional folds with NNW axes, D2 generated N-S shortening that curved the regional folds in an orthogonal way. D3 represents the last stage (ductile-brittle) of EW compression, with the formation of shear zones and thrust faults. In general, the units are metamorphosed between the amphibolite facies to high green schist, associated with the Anicuns-Itaberaí Metavulcanosedimentary Sequence and locally there are rocks in granulite facies, associated with the Anápolis-Itauçu Granulitic Complex. The Córrego Seco body was defined in the geological mapping of the final 2020 work, consisting of rocks that allowed for the characterization of a volcanic system called Anicuns. This work also highlights the economic aspects of the area, including mineral occurrences with potential for metallurgy (manganese, iron), agriculture (calcitic marble) and civil construction (wollastonite, gravel, clay).

    This work presents the results of the 1:50,000 scale geological mapping, performed in Anicuns, Goiás. The region is located in the Brasília Belt context,inserted at contact between the Anicuns-Itaberaí Metavulcanosedimentary Sequence (AIS) and the Anápolis-Itauçu Complex (AIC). This mapping aimed to characterize the geological units, starting with the literature review, photolithological, geochemical and geophysical interpretations. After the field stage and petrographic description, six lithostratigraphic units were defined. The AIS has three units mapped in the area, the basic-ultrabasic unit, which include tremolite-talc-schists, tremolitites and amphibolites, some serpentinized with mineralogical assemblages indicating amphibolite facies; carbonated rhythmic unit, which includes intercalations of quartzite magnetite, metalimestones, marbles and metarrhythmites, affected by reverse faults associated with thrust zones; and, psamopelitic unit represented by intercalations between quartz mica-schists (with or without garnet) and quartzites. The AIC represents gneiss rocks that underwent retrometamorphism leaving the granulite facies to high amphibolite, in the area they are identified as amphibolite orthogneisses with a composition containing quartz, biotite, epidote, garnet, plagioclase, hornblende and pyroxene being uralitized; and amphibolite paragneisses represented by biotite-muscovite gneisses, muscovite-garnet gneisses, garnet-muscovite-biotite schist with or without sillimanite and calciosilicate gneisses. Finally, the Tonian granitegneisses represented by the granodiorite creoulos with porphyritic, leucocratic texture, rich in biotite and muscovite, with the presence of hornblende also being common. The entire area is affected by three deformation phases associated with the third event of the Brasiliana Orogenesis (~790-545 Ma).
