Abstract | Este trabalho enfocou a avaliação de dados de radar (SAR) obtidos por aeronaves (experimento SAREX'92) e orbital (imageamento ERS-1) no mapeamento geológico da região do Salobo, Província Mineral de Carajás. Os principais objetivos da investigação envolveram a análise visual e digital dos dados SAR na discriminação litológica e mapeamento estrutural, levando-se em consideração, os distintos parâmetros funcionais dos sensores e da geometria de aquisição dos dados (polarização, resolução, ângulo de azimute e de incidência e sentido de visada). A pesquisa buscou também, fornecer subsídios aos modelos geológicos conhecidos da área teste e a avaliação da performance do futuro imageamento pelo RADARSAT. A área de estudo, com o mais importante depósito de cobre do país, está localizada na borda noroeste da Província Mineral de Carajás na continuidade do Cinturão de Cisalhamento Itacaiúnas, de suposta idade arqueana. Os resultados da pesquisa mostraram que os mais importantes parâmetros de radar foram ângulos de incidência, de azimute e sentido da visada. Os dados de radar do SAREX mostraram-se valiosos no mapeamento geológico na escala de semi-detalhe. Os dados ERS-1 exibiam distorções relativas a efeitos de "layover" e "foreshortening" nas áreas de relevo acentuado. Contudo, informações geológicas significativas puderam ser obtidas com estes dados, para as áreas de relevo arrasado. As técnicas de realce digitais mostraram-se valiosas na extração de informações com significado geológico, para os dois conjuntos de dados SAR avaliados. ABSTRACT: This work has focussed on the evaluation of airbone (SAREX'92) and orbital (ERS-1) SAR data in the geological mapping of the Salobo area, Carajás Mineral Province (Brazilian Amazon Region). The main objectives of the investigation have ancopassed visual and digital analysis of the SAR data in the lithological discrimination and structural mapping taking into account distinct sensor parameters and acquisition data geometry (polarization, resolution, incidence and azimuth angles and look direction). The research has also aimed at providing insights for the geological knowlegde of the Salobo area and for the RADARSAT evaluation in this "difficult" tropical rain forest environment. The test-site is inserted in the Itaiúnas Belt, a wide shear zone with probable Archean age and copper deposits, located in the northwest border of the Carajás Mineral Province. The results have shown that the most important radar parameters were incidente and azimuth angles and look direction. Airborne radar data from SAREX proved to be a valious tool for geological mapping at a semi-detailed scale. ERS-1 data has presented distortion problems related to "layover" and "foreshortening" affects in the high relief area. However, geological information could be extracted in the low relief regions. Digital enhancement techniques proved to be important in the extraction of information with geological meaning from both SAR dataset. |
