Sb isotope fractionation of strong Chemical Weathering in Tropical

This study aims to explore the mechanism of antimony (Sb) isotope fractionation during chemical weathering and soil biogeochemical processes, which has important implications for the Sb isotope composition in the hydrosphere. We analyzed the major and trace element contents and Sb isotope composition along an 8 m deep basalt weathering profile in the Huguangyan area of Guangdong Province in southern China.
