                         important geological archives for understanding the origin, 
                         evolution and controls of the largest fluvial drainage basin on 
                         Earth. Climate has been most often claimed as the main factor 
                         affecting river evolution in this region. An increasing volume of 
                         publications have also highlighted tectonics as a relevant 
                         control. This work investigates the late Quaternary evolution of 
                         the Madeira River, the biggest southern tributary of the Amazonas 
                         Basin and a major waterway in South America, with the goal of 
                         discussing the factor with highest potential of influence on its 
                         development in space and time. The approach consisted of carrying 
                         out a detailed morphological, sedimentological and chronological 
                         characterization of terrace deposits. Three terraces were 
                         recognized, which record sandy/pebbly channel, muddy channel/oxbow 
                         lake, point bar, floodplain, as well as crevasse channel, crevasse 
                         splay and levee deposits. The topographically highest terrace T1 
                         formed in the time interval before 43,500 and 31,696-32,913. cal. 
                         yrs BP, the intermediate terrace T2 between 25,338-26,056 and 
                         14,129-14,967. cal. yrs BP, and the lowest terrace T3 between 
                         12,881-13,245 and 3158-3367. cal. yrs BP. These terraces are the 
                         testimony of successive downcutting and sediment aggradation. 
                         Episodes of terrace erosion and deposition cannot be fully 
                         accommodated within the framework of fluctuating river base level 
                         tied to Late Pleistocene-Holocene global or regional climate 
                         fluctuations. Changes in tectonic subsidence rates might have 
                         played an important role in the equilibrium state of this
