Contribution of Asian dust to soils in Southeast China estimated with Nd and Pb isotopic compositions

Asian dust has been identified in subtropical soils of China. Neodymium (Nd) and lead (Pb) elemental and isotopic geochemistry of soils in Southeast China were used to assess the significance of local versus extraneous sources. The eNd(0) values were close to the parent rocks (+ 2.9) in the young soils (NSJ); while their values were always negative (~ − 3.7) in the old soils (OMJ), implying dust deposition. The young soils contained less Asian dust contribution (
