The texture and sources of the sediment captured in the sediment trap. (a) Grain-size distribution of sediment trap samples. (b) Tertiary plot of the three representative clay minerals showing differential affinity of the sediment trap samples to four hypothesized fluvial sources of Changjiang River, Oujiang River, Minjiang River, and Zhuoshui River. Note: the fluvial sources were based on (ref.28).
