The Paraná River basin is one of the largest hydrological systems in South America (~2.6 x 106 km 2 ). Most large rivers exhibit transverse and longitudinal inhomogeneities downflow the confluence of tributaries, which can be detected for tens or even hundreds of kilometers (e.g., Yang et al., 1996). A noticeable cross-sectional chemical asymmetry regarding the major dissolved constituents was earlier distinguished in the Middle Paraná River, after the confluence of its main tributaries, i.e., the Paraguay and Upper Paraná rivers (Drago and Vasallo, 1980). In this study we present new chemical and stable and radiogenic isotopic data of the Paraná River drainage basin in order to explain the dissimilar composition of water observed across the main channel of the Middle Paraná River.
