The Chuanjiang River receives most of the sediments fed by the Upper reaches of the Yangtze River. It is important to study the magnetic characteristics of the Chuanjiang River and the main tributaries which play an important role in the research of origin of the Three Gorges and evolution of the Yangtze River. Our research helps to better understand the magnetic characteristics of the Chuanjiang River and the main tributaries. Several conclusions can be made according to our research. (1) Magnetic characteristics are different at different parts of the trunk river. Both samples at Luolong and Hejiang have the lowest χ_lf and least ferrimagnetic (FM) minerals. The sample at Fengdou has the lowest χ_fd%, also with the lowest content of superparamagnetic particles. (2) Magnetic characteristics are also obviously different between the tributaries. Magnetic minerals from Jinhajiang and Wujiang have bigger crystals than other tributaries and are almost ferrimagnetic, which dominate the magnetic characteristics of the samples. Jialingjiang has the lowest content of ferrimagnetic (FM) minerals of all the tributaries of the Chuanjiang River. Many incomplete antiferromagnetic minerals exist in the Chishuihe sediments. (3) Magnetic parameters of the samples from the trunk river vary in a wider range, also with worse correlation compared with the samples from main tributaries. This may be related to the larger drainage basin and more complicated provenance that the trunk river has. (4) Co- parison ofmagnetic characteristics between the trunk river and main tributaries shows that magnetic characteristics of the Chuanjiang River are restricted by the Jinshajiang River and has not been changed by the afflux of the tributaries. So supracrustal rocks above Yibin dominate the magnetic characteristics of the Chuanjiang River.
