                         and its impact on large Amazonian rivers have been of continuous 
                         research interest. Despite the low relief of the land surface, 
                         which has generally been attributed to tectonic stability, there 
                         is increasing evidence of Neogene fault reactivation within 
                         central Amazonia. Recent research has also reported surface 
                         folding during the Quaternary, but this record was based only on 
                         morphological analysis of remote sensing data. This investigation 
                         focuses on a megascale (~60,000 km2) domal relief from central 
                         Amazonia (the Juru{\'a} dome). It firstly aims to verify the 
                         domal relief relationship to folding. It then explores the origin 
                         of the stress field from which it has developed within the context 
                         of Andean uplift and the westward movement of the South American 
                         plate. The approach consisted of analyzing river adjustments based 
                         on morphological and morphometric information from remote sensing 
                         imagery, integrated with subsurface data Bouguer gravity and 
                         magnetic anomaly maps, well logs, and seismic reflection sections. 
                         The results revealed that the Juru{\'a} dome coincides with the 
                         location of a basin depocenter. Subsurface evidence exists for the 
                         growth of a broad anticline producing thicker sedimentary units 
                         away from the dome core. NE- and NW-striking normal and reverse 
                         faults with flower structure geometries are abundant and suggest 
                         deformation from strike-slip tectonics. Gravity and magnetic data 
                         revealed that the fold and many of its associated faults are 
                         deep-rooted into basement rocks. Within the analyzed stratigraphic 
                         interval, faults are mostly developed into pre-Cretaceous units, 
                         but often propagate to the surface, where they define the edges of 
                         the dome and partly deform its overall shape. The fold and its 
                         related faults have modified the course of several rivers within 
                         the domal relief area, including the Juru{\'a} River, which is 
                         entrenched along NE-striking faults that are configured to release 
                         stress along the fold axis. The geomorphological and structural 
                         data are collectively compatible with a long-term NW-trending 
                         maximum horizontal compressive stress-field that is driving basin 
                         inversion. This neotectonic activity can be linked to far-field 
                         stresses from the pushes from the Andean orogeny and the movement 
                         of the South American plate against the North Andean and Nazca 
                         plates.",
