文章阐述了通过固体同位素质谱仪,采用同位素质谱稀释分析方法(ID-TIMS)和电感耦合等离子体原子发射光谱(ICP-AES),意外地在山西发现钐(Sm)和钕(Nd)元素含量异常的数据,进而与多家单位合作,采用多种现代分析手段精密分析与研究,最终在山西沁源大峪铝土矿和平陆曹川黑灰色黏土岩与铝土岩中发现稀有稀土含量的异常值,该值达到稀土金属矿床工业指标。
The article describes the unexpected discovery of Sm and Nd in Shanxi by solid-state isotope mass spectrometry (ICP-AES) using isotope mass spectrometry (ID-TIMS) and inductively coupled plasma atomic emission spectrometry Abnormal data, and then with a number of units, the use of a variety of modern analytical methods of precision analysis and research, and ultimately in Shanxi Qinyuan Dayu bauxite and Ping Lu Cao Chuan dark gray clay rock and bauxite found rare earth content Outliers, the value reached the industrial indicators of rare earth metal deposits.
