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.

本研究旨在探讨化学风化与土壤生物地球化学过程中锑（Sb）的同位素分馏机制，该机制对水圈中的锑同位素组成具有重要的指示意义。我们对中国南部广东省湖光岩地区一处8米深的玄武岩风化剖面开展了常量与微量元素含量及锑同位素组成分析。
