There is a little published data availability on mineralogy and textural behavior of the Ganga and its tributary River Tons. Moreover, there is no published data available related to the nature of sediment mixing at this river confluence. Therefore, this project work will break new grounds to understand the fluvial behavior of the Ganga and its tributary River Tons. Sedimentology of the Ganga and the Tons Rivers has been worked out utilizing the grain size analysis, sediment mixing pattern and mineralogical analyses of the sediments. Sediment-mixing pattern of the Ganga and the Tons River is calculated by the theoretical method. Minerals identification of the Ganga and the Tons River are found out with the help of stereo, petrological microscope and by X-Ray diffractometer. Heavy mineral assemblage of these Rivers studied to analyze provenance. Sediments of the Tons River are derived from sedimentary with little contribution of pegmatite and low rank metamorphic rock. Sediments of Ganga river are derived from multiple source area type consist the sedimentary, igneous & high rank metamorphic rocks.
