O Papel da Aerogamaespectrometria, da Aeromagnetometria e do Sensoriamento Remoto na Caracterização de Terrenos Greenfield do Cráton Amazônico: Resultados e Desafios na Discriminação de Alvos Exploratórios na Província Mineral do Tapajós

The investigation of greenfield terrains through the airborne geophysics dataset provides valuable information about the geologic context and, mainly, the metalogenetic understand. Almost exclusively, there are available regional (low resolution) airborne geophysical data, like gamma-ray spectrometry and magnetic data, and, in this context, some information about the geology can be interpreted. But, the use of high resolution data, like the gradiometer magnetometry, and remote sensing images increases the potential of applications for the characterization of these terrains, like the vast area of the Amazon craton. The Tapajós Mineral Province, located in the states of Amazonas and Pará (Brazil), was selected as a case study in this paper for the recognition of the potential targets for mineral exploration.
