             abstract = "The Amazon basin has most of the largest rivers of the world. 
                         However, works focusing the geological evolution of the trunk 
                         river or its tributaries have been only partly approached. The 
                         Branco River constitutes one of the main northern Amazonian 
                         tributaries. A previous work proposed that, before flowing 
                         southward into the Negro-Amazon Rivers, the Branco River had a 
                         southwest to northeast course into the Caribbean Sea. The present 
                         work aimed to establish if the proposed change in the course of 
                         this river is supported by morphological and sedimentological 
                         data. Other goals were to discuss the factors influencing river 
                         development and establish its evolution over time within the 
                         chronological framework provided by radiocarbon and optically 
                         stimulated luminescence dating. The work considered the entire 
                         course of the Branco River downstream of the Precambrian Guiana 
                         Shield, where the river presumably did not exist in ancient times. 
                         The river valley is incised into fluvial sedimentary units 
                         displaying ages between 100 and 250 ky old, which record active 
                         and abandoned channels, crevasse splay/levees, and point bars. The 
                         sedimentary deposits in the valley include two alluvial plain 
                         units as old as 18.7 ky and which intersects a Late Pleistocene 
                         residual megafan. These characteristics suggest that a long 
                         segment of the Branco River was established only a few thousand 
                         years ago. Together with several structural anomalies, these data 
                         are consistent with a mega-capture at the middle reach of this 
                         river due to tectonic reactivation in the Late Pleistocene. This 
                         integrated approach can be applied to other Amazonian tributaries 
                         to unravel how and when the Amazonian drainage basin became 
                         established.",
