                         Mineral Province (Brazilian Amazon Region) since the beginning of 
                         the 1990s. The Province, with a heterogeneous relief and almost 
                         totally covered by tropical rainforest, is part of the 
                         Itacai{\'u}nas Shear Belt within the Amazonian Craton. The area 
                         is world-wide known due to its mineral potential. However, from 
                         the tectono-stratigraphic viewpoint it is still problematic due to 
                         several drawbacks such as poor access, physiographic complexity, 
                         and detailed information available only in few isolated sites 
                         (mining, deposits or mineralizations). Spaceborne optical (Landsat 
                         TM) and radar (C-HH RADARSAT-1) imageries and digital integrated 
                         products (RADARSAT-1/Aerialgammaspectrometry) have been 
                         extensively applied for geological mapping purposes in the 
                         Province. Due to their synoptic view coupled with distinct 
                         sensor/terrain geometry allowing the extraction of indirect 
                         geological information, these kinds of remotely sensed products 
                         have been interpreted based on specific morphostructural 
                         criteria., with the following objectives: (1) to integrate 
                         previous and disperse geological data; (2) to explore the 
                         identification of regional structures and distinct 
                         tectonic-stratigraphic regimes on a large mapping scale; (3) to 
                         distinguish different motion phases along the Itacai{\'u}nas 
                         Shear Belt (WNW-ESE trending) and characterize related rock 
                         forming and deformation events. Fieldwork campaigns carried out 
                         along selected profiles have provided new information. These 
                         findings were integrated with previous data and have allowed the 
                         production of a new tectono-stratigraphic map for the Province 
                         (1:250,000 scale). In addition, it was also possible to 
                         characterize three ductile and brittle transpression phases, 
                         locally transtensive, with Archean/Neoproterozoic ages. It was 
                         also observed extensive reactivations with pulses at the end of 
                         the Proterozoic and beginning of the Palaeozoic, at the Mesozoic 
                         and at the Tertiary. Volcanism, sedimentation, granitogenesis, 
                         metamorphism and deformation with distinct intensity are 
                         associated with these phases. The records of these deformations 
                         are clear in orbital remote sensing images and can be used as 
                         diagnostic of the distinct motion/deformation events in the 
                         Province. These orbital images are fundamental tools for 
                         tectono-stratigraphic mapping purposes in the Province.",
