| Abstract | The purpose of this work is to evaluate Landsat-MSS data processing techniques for lithostratigraphic discrimination in Central Brazil. Two areas were chosen for presenting good geological maps with significant variety of stratigraphic units that guarantee adequate control of.results: 1. Ceres/Rubiataba area with: granite gneissic basement; high grade granulitic terrains; amphibolitized oceanic crust with associated meta-vocano-sedimentary rocks of probable Lower Proterozoic age; metassediments of Middle Proterozoic age; and 2. Sao Domingos area with: granite-gneissic basement; low grade metamorphic volcano-sedimentary sequence cut by tonalitic and granite stocks of probable Lower Proterozoic age; platformal carbonatic and pelitic deposits of Upper Proterozoic age (Bambui Group); continental Cretaceous sandstones; residual sand deposits. Geological maps were digitalized to match the Landsat images as overlays in the view screeen. A supervised thematic classification was run using computer-generated training sites that correspond to studied outcrops coordinates. Other digital techniques of image enhancement were run and are discused elsewere. The multispectral analysis applied to geological cartography proved that much more research has yet to be done. Some steps are suggested for future tests and implementation. RESUMO: O objetivo deste trabalho foi avaliar tecnicas de processamento de dados Landsat-MSS para discriminacao litologica no Brasil Central. Duas Areas foram escolhidas por apresentarem bons mapas geologicos com variacoes significativas de unidades estratigraficas que garantern um controle adequado dos resultados: 1. Area de Ceres/Rubiataba, com: embasamento granito-gnfissico; terrenos granulicos de alto grau; crosta oceanica anfibolitizada associada a rochas tavulcano-sedimentares de idade, provavel do Proterozoico Inferior; 2. Area de Sao Domingos, com embasamento granito-gnassico; sequencia metamorfica vulcano-sedimentar de baixo grau cortada por stocks tonaliticos e graniticos de idade provavel do Proterozoico Inferior; depositos carbonaticos e peliticos do Proterozoico Superior (Grupo Bambui; arenitos cretaceos continentais; depositos de areias residuais. Mapas geologicos foram digitalizados de modo a se justapor como overlays na tela. Uma classificacao tematica supervisionada foi feita usando estacoes geradas por computador, correspondentes a coordenados de afloramentos estudados. Outras tecnicas digitais de melhoramento de imagens sao discutidas em outra comunicacao. A analise multiespectral aplicada a cartografia geologica provou que a necessfiria muita pesquisa ainda. Alguns passos sao sugeridos para testes futuros e implementacao. |
