Abstract: Magnetic measurements and particle size analysis were carried out on samples collected from the tributaries in summer of 2009, with the purpose to recognize the difference in magnetic properties among them. The results indicate that the magnetic properties of the sediments are dominated by both magnetite and hematite, which reflects the fluvial input from Mesozoic red beds widely distributed in Sichuan Basin. Sediments from the main stream of Jialing River are characterized by higher proportions of magnetite due to loess input in the upper reach. A combination of magnetic parameters of χ, SIRM and S-300 can discriminate the sediments from the three tributaries very well.
