Seasonal geochemical heterogeneity of sediments from a subtropical mountainous river in SE China
Abstract The Zhe Min mountainous rivers in SE China are characterized by stable tectonics, small mesoscale drainage basins, relatively homogenous bedrocks, dense vegetation cover and high rainfall conditions. These rivers deliver loads of sediments and nutrients to the oceans and always indicate considerably high variability of sediment flux on short term timescales. However, short term sediment compositional variations and transport mechanism by these mountainous rivers remain poorly understood. Here we target the Minjiang River, use mineralogical and trace element geochemical data of suspended particulate matters (SPMs) within a one year hydrological cycle (from October 2016 to October 2017) riverbed sediments
