Resumo: Remote sensing has presented a wide range of applications in recent years, among them there is the one that allows the identification of possible targets of minerals without the need to be present in the field, through the interaction between matter and the electromagnetic energy emitted by a certain source. In the regions of Canindé de São Francisco/SE and Gararu/SE there are indications of several occurrences of metallic minerals, such as lead (Pb), copper (Cu), manganese (Mn) and iron (Fe), and to identify these occurrences, magnetic data, band combination techniques and remote sensing image processing methods were used in the visible, near-infrared and short-wave infrared bands of the Landsat 8 and Sentinel-2 satellites. The results presented by the applied techniques showed different characteristics, indicating the possible identification of exposed targets of iron oxides, hydroxyl minerals and areas of vegetation. By comparing the results for the different regions, the presence of similar characteristics is noted, pointing to the possibility of the existence of ferrous minerals in both analyzed regions. To verify the results, samples were collected at specific points, previously defined, which were analyzed using elemental characterization by X-ray Fluorescence (FRX) and mineralogical characterization by X-ray Diffraction technique (XRD).

Dentre elas existe a que permite a identificação de possíveis alvos de minerais sem a necessidade de estar presente em campo, por meio da interação entre a matéria e a energia eletromagnética emitida por uma determinada fonte. Nas regiões de Canindé de São Francisco/SE e Gararu/SE existem indícios de várias ocorrências de elementos químicos, como chumbo (Pb), cobre (Cu), manganês (Mn) e ferro (Fe), e para identificar essas ocorrências foram utilizados dados magnéticos, técnicas de combinações de bandas, e métodos de processamento de imagem de sensoriamento remoto nas bandas do visível e infravermelho de ondas curtas dos satélites Landsat-8 e Sentinel-2. Os resultados apresentados pelas técnicas aplicadas demonstraram diferentes características, indicando a possível identificação de alvos expostos de óxidos de ferro, minerais de hidroxila e áreas de vegetação. Por meio da comparação entre os resultados para as diferentes regiões é notado a presença de características semelhantes, apontando a possibilidade de existência de minerais ferrosos em ambas as regiões analisadas. Para verificação dos resultados, foram coletadas amostras em pontos específicos, previamente definidos, as quais passaram por análise utilizando a caracterização elementar de Fluorescência de raios X (FRX) e mineralógica por Difração de raios X (DRX).Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqSão CristóvãoporSensoriamento remotoSatélitesMinérios de ferroRemote sensingSatellitesIron oresCIENCIAS EXATAS E DA TERRA::FISICACaracterização de minérios de ferro por sensoriamento remoto no semiárido sergipanoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPós-Graduação em FísicaUniversidade Federal de Sergipe (UFS)reponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessLICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/17549/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALRAFAEL_MARLLUS_SANTOS.pdfRAFAEL_MARLLUS_SANTOS.pdfapplication/pdf7145527https://ri.ufs.br/jspui/bitstream/riufs/17549/2/RAFAEL_MARLLUS_SANTOS.pdfd862002d06ac2bcc7dcac61be1568df1MD52TEXTRAFAEL_MARLLUS_SANTOS.pdf.txtRAFAEL_MARLLUS_SANTOS.pdf.txtExtracted texttext/plain136795https://ri.ufs.br/jspui/bitstream/riufs/17549/3/RAFAEL_MARLLUS_SANTOS.pdf.txt6115c606fb1e0bb52453e53494bb2d72MD53THUMBNAILRAFAEL_MARLLUS_SANTOS.pdf.jpgRAFAEL_MARLLUS_SANTOS.pdf.jpgGenerated Thumbnailimage/jpeg1224https://ri.ufs.br/jspui/bitstream/riufs/17549/4/RAFAEL_MARLLUS_SANTOS.pdf.jpg13d980f654dace2e415842ed57835f79MD54riufs/175492023-05-16 09:13:20.924oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2023-05-16T12:13:20Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false
