Kaolinite genesis and the formation of REE ion adsorption deposits.

X-ray diffraction was used to confirm the purity and lack of change in mineralogy of kaolinite clays following a chemical purification procedure. The samples were then used for stable isotope analysis as part of the study 'Kaolinite genesis and the formation of REE ion adsorption deposits'.

本研究先对高岭石黏土实施化学提纯工艺，随后采用X射线衍射（X-ray diffraction）技术验证其纯度及矿物学特征未发生改变。所获样品随后被用于稳定同位素分析，作为研究《高岭石成因与稀土元素（Rare Earth Element，简称REE）离子吸附型矿床的形成》的组成部分。
