                         Xingu River divide were the scene of intense neotectonic activity 
                         (Miocene-Holocene), which are here highlighted based on remote 
                         sensing images of the microwave bands: SRTM and PALSAR. The images 
                         in the SRTM highlight the topography and the ones in the PALSAR 
                         highlight the identification of paleochannels in plane lands in 
                         the alluvial fan. The presence of paleochannels of various ages, 
                         the tilting and the separation of the island of Maraj{\'o} from 
                         the continent, with reflexes in the captures of the rivers 
                         Tocantins and High Anapu which were part of the drainage basin of 
                         the Amazon Basin as well as the formation of a large alluvial fan 
                         at the mouth of the River Tocantins, attest the neotectonic 
                         activities in the studied region. The following radargeologic 
                         units were identified: igneous-metamorphic basement from the 
                         Paleoproterozoic; volcano-sedimentary sequence from the 
                         Neoproterozoic; siliciclastic sediments with dominance of psamites 
                         from the Cretaceous; lateritic paleogenic covers; lateritic 
                         neogenic covers, alluvial fans from the Plio-Pleistocene; 
                         pleistocenic terraces and holocenic alluvions. Systems of dextral 
                         transtensional faults with about E-W orientation and normal faults 
                         to N-S orientation were the main movement acting in the region. In

                         and the \2 (vertical) . While the \3 
                         (horizontal) are disposed according the N-S orientation. The 
                         metallogenetic implications consist that the laterites are better 
                         developed with bauxite and kaolin to the North and the South of 
                         the studied area , where altitudes are more higher.",
