| Abstract | Foram selecionadas duas áreas teste (Folha Serra dos Carajás e a área do Pojuca) situadas na Província Mineral de Carajás para investigação geológica. Utilizou-se nesta pesquisa os dados gamaespectrométricos adquiridos durante os anos de 1975 e 1976, que se referem aos aerolevantamentos do Projeto Geofísico Brasil-Canadá. Os perfis gamaespectrométricos foram coletados, através de linhas de voo posicionadas segundo a direção N-S e espaçadas de 1 km, com intervalo de amostragem igual 61m. Tais perfis convertidos, inicialmente, em grades regulares com resolução de 625 x 625 m, foram transformados em imagens digitais com resoluções de 125 x 125 m e 30 x 30 m (reamostragem), As imagens gama individuais, combinadas e integradas as imagens TM/LANDSAT, foram analisadas, através das técnicas de processamento digital de imagens (composições coloridas, transformações por componente principal, decorrelação e IHS); bem como visualmente. Os produtos analisados, quando comparados aos mapas geológicos (na escala regional e de semi-detalhe), mostraram que existem fortes correlações espaciais entre as unidades litoestratigráficas, as feições estruturais e os padrões radiométricos. Além disso, foi observado que os dados aerogamaespectrométricos digitais integrados às imagens TM/LANDSAT, constituem-se em uma ferramenta poderosa para o mapeamento geológico e programas de exploração mineral neste ambiente amazônico com floresta tropical. ABSTRACT: Two test-sites, covering the Serra dos Carajas sheet (56, 5 x 56, 5 km) and the Pojuca belt (15, 4 x 15, 4 km) were selected for geological investigation. Gammaspectrometric airborne data (eU, eTh, Total Count and eU/eTh) were acquired over part of the Serra dos Carajas Mineral Province (Brazilian Amazon Region) during the 1975 and 1976 (PGBC - Brazil-Canada Geophysical Program) campaigns. The original data were collected in NS profiles (1 km apart and 61 meter samples along the profiles). The gamma spectrometric data were converted twice, first to a 625 x 625 m grid and then to a 125 x 125 m grid (resampling). The 125 x 125 m data were transformed into digital images with cells of 125 x 125 m and 30 x 30 m. Isolated and combined gamma images were analysed by digital enhancement techniques (color composites, principal component, analysis decorrelation stretch and IHS transform) and visual examination. The UTM registered gamma and TM/Landsat images were integrated through IHS transform. The enhanced products were compared to geological maps and this comparition has demonstrated that lithostratigraphic units and structural features registered on both data source are perfectly concordant. In addition, the research has provided insights regarding the knowledge of the geological model in the study areas. Gamma airborne data whether isolated or integrated with orbital remote sensing data have proved to be a powerful tool for geological mapping and mineral exploration programs in this rain forest Amazon environment. | ||||||
