Accumulating conditions of vermicular red earth in South China have been explored for decades,but its origin and sedimentary environment are still unknown. Based on the analysis of physico-chemical properties of 130 samples which were sampled from Jiujiang Xinzi,and Shahe in Jiangxi Province,Jinhua and Anji in Zhejiang Province,and Zhuzhou in Hunan Province,the authors try to have a better understanding of how vermicular red earth(VRE)was accumulated. Particle size of the soil samples was measured using the Malvern 2000,major elements using XRF,REE using ICP-MS,and isotope ratios of Sr and Nd using TIMS.
