Antimony isotopic composition of the upper continental crust

This study aims to estimate the Sb isotopic composition of the upper continental crust，which is key to studying Sb transport and transformation in the supergene environment . We collected a set of well-characterized granites, granodiorites, sedimentary rocks, loess and stream sediments from the upper continental crust for Sb isotope analysis.本研究旨在估算上陆壳的锑（Sb）同位素组成，这是开展表生环境中锑迁移与转化研究的关键。我们采集了一套来自上陆壳、经过详细表征的花岗岩、花岗闪长岩、沉积岩、黄土及河流沉积物，用于锑同位素分析。
