Intrusão Alcalina de Morro Preto (go): Geologia, Petrografia e Geoquímica

A intrusão alcalina de Morro Preto, localizada ao norte da cidade de Piranhas (GO), corresponde a um corpo irregular a subcircular com aproximados 3,34 km2 alojado em gnaisses atribuídos ao Arco Magmático de Goiás. É constituída principalmente por carbonatitos e lamprófiros com graus variados de laterização e silicificação, além de silexitos e, em menor expressão, por sienito ferruginizado e basalto alcalino. Quimicamente mostram baixas concentrações em Cs, K, Na, Rb e altas concentrações em elementos como TR, Nb, Ba, Th e U. Isto aparenta resultar de processos de laterização/silicificação e da formação de fases minerais raras (ou neoformação de fases minerais), como fosfatos com alta concentração de TR e Th, oxi-hidróxidos de Fe, Ba, Mn, e oxi e/ou silico-fosfatos de ETR, Nb, Ta, dentre outros, e a formação de barita. A presença de rochas carbonatíticas com alto P2O5 e o enriquecimento acentuado em TR sugere a possibilidade de mineralizações destes componentes, similar às observadas em outros complexos alcalinos de Goiás e de Minas Gerais, como Catalão e Araxá. A distribuição de elementos menores, traços e TR mostram que as rochas são produtos de alteração de rochas ígneas alcalinas como carbonatitos, lamprófiros e basaltos alcalinos, rochas já enriquecidas em elementos como Th, U, TR (principalmente em ETRL), Nb e Ta. Os teores anormalmente altos são resultado do processo de enriquecimento supérgeno (processos de intemperismo como silicificação e laterização) e/ou alteração hidrotermal com baixa temperatura.

Avaliação da dinâmica temporal da evaporação no reservatório de Itumbiara, GO, utilizando dados obtidos por sensoriamento remoto

The object of this work was to study the dynamics of evaporation in the Itumbiara reservoir, located in Central Brazil, using MODIS-derived water surface temperature (product MOD11A1) and meteorological data acquired over the water surface. The evaporation rates were derived from latent heat flux, estimated through a mass transfer model. The estimates were carried out for the period between 1/1/2010 and 31/12/2010. The results showed that evaporation rate tends to increase from January to September and then decrease from September to December. The evaporation rate reached values near 20 mm day-1 in Itumbiara reservoir during the dry season in 2010. The mean evaporation rate for the wet season was 3.66 mm day-1 and 8.25 mm day-1 for the dry season. The total water volume evaporated from Itumbiara reservoir during 2010 was estimated at about 1.7 billion m³ (2,300 mm) which represents 10% of total reservoir volume. The results suggest that advection is the main transport mechanism which drives the evaporation in Itumbiara. The convective processes contribute secondarily to evaporation in Itumbiara reservoir.

Modelo estrutural do maciço rochoso do Depósito de Cobre e Ouro da Mina da Chapada, Alto Horizonte, GO

The Cu-Au mine of Chapada is located in the municipality of Alto Horizonte, in the northwestern portion of Goiás state and is inserted in the geological context of the Brasilia Belt, specifically the Mara Rosa Magmatic Arc, which hosts important deposits of Au and Cu-Au. The rocks found in the study area belong mainly to the Volcano-Sedimentary Sequence of Mara Rosa and are composed of basic to acidic metavolcanic rocks, psammiticpellitic metasedimentary rocks, chemical rocks and also hydrothermal products. Late intrusions occur and are represented by pegmatitic dikes and tonalitic bodies. The ore deposit of the Chapada mine is formed predominantly by the chalcopyrite-pyritemagnetite association, where pyrite is the most abundant mineral. Through the structural mapping of the mining fronts, it was able to recognize three deformational phases (Dn, Dn +1, Dn +2). During the Dn phase, isoclinal recumbent folds were formed, in association with amphibolites facies metamorphism. Later, in phase Dn +1, there was formation of drag folds and intrafolial folds in association with retrograde metamorphism in the greenschist facies. The deformational phase Dn +2, in its turn, was responsible for late symmetrical folding of the foliation, with NS and EW axes, resulting in an interference pattern of the dome-and-basin type

Caracterização geológica e estrutural da porção centro-norte do greenstone belt de Faina, Faina-GO

The area where the study was conducted is located in the central-western state of Goias. It geologically inserts the northern portion of the Greenstone Belt of Faina which belongs to the Archean terranes that fits in Brasília Fold Belt and Tocantins Structural Province. This region is known for its greenstone lode gold potential and it was heavily exploited by pioneers and prospectors, leaving many records for where they have been through. Preliminary work done by Orinoco Brasil Mineração in their required areas at the region showed that the environment is promising for gold mineralization and that the ore is controlled by structures. Therefore the objectives of this work were the geological and structural mapping in semi detail scale to improve geological, stratigraphic and structural controls present attributing possible ore understanding. With the development of the work there were recognized on the desktop three structural domains separated by a thrust fault. For each domain were discriminated the geological units ranging in gneisses, quartzites formed from coarse sediments arcoseanos, and schists. By mapping structures there were found five deformation phases, Dn-2, Dn-1, the Dn event that generated the main foliation (Sn) in high representation and two post-stages Dn with brittle late manifestations. The detail mapping of the Rattlesnake Gallery showed that the mineralized quartz vein is consistent with axial-plane foliation Sn-2 belonging to the oldest deformation Dn-2 phase and that the high grade is distributed in the hinge region folds of the same phase

Mapeamento geológico e petrografia do alvo T-578 - Greenstone Belt Pilar de Goiás (Pilar de Goiás - GO)

The study area is located in the geological parameters of the Pilar de Goiás Greenstone Belt (GO), it is part of the Pilar de Goias Group’s meta-volcano-sedimentary sequence. This is a homoclinal package constituted by terrigenous metassediments containing intercalations of meta-ultramafic rocks and iron formations. The units that were informally named in this work, are interpreted as belongs to the Serra do Moinho Formation. Through mineralogical associations the area’s metamorphism were classified as high greenschist facies garnet zone. Prior to this work were detected in the area, through soil samples, some auriferous anomalies. One of the objectives of this work is the detection of possibles hidrotermal alterations related to these anomalies presents in the study area

Caracterização petrográfica dos alvos Hidrotermalitos Norte e Sul, Suruca e porção NW da Mina de Chapada - Alto Horizonte, GO

Main occurrence of Cu-Au in Goias Magmatic Arc, the Chapada mine fits into the geological context of the Brasilia Fold Belt, specifically in the Mara Rosa Magmatic Arc. Four targets, named Hidrotermalito Norte and Sul, NW Chapada Mine Portion and Suruca, are situated in this context, which includes ortogneisses and rocks from the Mara Rosa volcanic-sedimentary sequence. All these targets have been studied due to the possibility of presenting a great potential in Cu-Au, as well as the Chapada mine. Hidrotermalitos Norte and Sul targets presents four lithological sequences, which were identified as: quartz-muscovite schist; muscovite quartzites and kyanite quartzites; quartz-biotite-amphibole schist with pyrite and epidote-amphibole-biotite gneisses with muscovite; muscovite-biotite gneisses. They are metamorphosed to amphibolites facies and retrogressive greenschist facies. Sulfetation represented mainly by pyrite. In the NW Chapada Mine Portion, three main lithological groups were identified and classified as biotite gneisses; honblende-quartz-biotite-schist; amphibolites, with the first group metamorphosed in greenschist facies (low grade), and the other two groups metamorphosed in amphibolites facies, with subsequent retrogressive metamorphism in greenschist facies. Sulfetation is represented by chalcopyrite and pyrite. Finally, also three main lithological groups were identified in the Suruca target, classified as garnet-chlorite-epidote-eiotite gneiss; biotite gneiss and chlorite-biotite gneiss with epidote and muscovite; muscovite-quartz schist, all them metamorphised in amphibolites, with retrometamorphism in greenschist facies. Sulfetation represented by pyrite and sphalerite

Caracterização metamórfica do Greenstone Belt de Guarinos - GO

The study area comprises Guarinos Greenstone Belt which is located in the centralwest state of Goias and has an approximate size of 280 km2. The present work has as main objective to characterize the metamorphism of the greenstone belt and the relationship between the tectonic events and the metamorphism. For the execution of the work we used data collected in the course Geological Mapping of Crystalline Area of the geology course of UNESP, classes 2009 and 2010, the data collected by Alex Choupina Joaquim Andrade Silva in his master's thesis and the information collected in field in the study area. This compilation of data allows approximately 200 thin sections have been evaluated and allowed the construction of the metamorphic map in scale 1:125.000, also allowed the preparation of the geological map in scale 1:125.000 greestone belt, based on 1:25.000 scale maps performed by students of UNESP and the mapping conducted by Silva (2011). The study area was divided into two tectonic compartments depending on the Shear Zone Engenho Velho that longitudinally crosses study area, with direction approximately NW-SE. The west compartment is bordered by granite-gneiss complex and the east compartment, seems thicker to the south and narrows gradually towards the north and its structure is seen in general as a great monoclinal with NW-SE direction with trim to SW, this way your stack was considered as a package of rocks at the base and metaultramafic metamafic the top, with a second package in tectonic contact, which is composed of detrital and chemical metasedimentary rocks. The east compartment is represented by the intrusion of a large granitic body surrounded by amphibolites and metasediments, is bounded on the east by a granite-gneiss complexes through thrust fault, and is bounded on the west by the other compartment. The structure of the compartment is seen as a major axis oriented roughly... (Completo abstract click electronic access below)
