岩矿鉴定和电子探针在矿物药金礞石鉴定及质量评价中的应用

Application of rock and mineral identification and electron probe in the identification of mineral medicine lapis micae aureus and quality evaluation

采用薄片鉴定和电子探针测试对来自个6个不同地区的金礞石进行鉴别和质量评价。首先通过薄片鉴定初步确定金礞石样品的主要成分及伴生矿物,进一步利用电子探针技术对金礞石的主要成分、伴生矿物进行半定量分析,再利用电子探针波谱定量分析研究金礞石中Hg、Pb、S、Ge等元素的赋存状态,在这些技术综合鉴定的基础上,对各地的金礞石进行质量评价。研究表明,岩矿鉴定及电子探针技术的结合用于鉴定金礞石矿物药是一种极为有效、可行的办法,具有原位、无损的优点。

In this paper,the identification and quality evaluation of lapis micae aureus from six different areas are carried out by using chip identification and electron probe test.First of all,the main components and associated minerals of lapis micae aureus samples are preliminarily determined through the chip identification.Then,the semi-quantitative analysis is carried out on the major components and associated minerals of lapis micae aureus by means of the electron probe technology.The occurrence state of Hg,Pb,S,Ge and other elements in lapis micae aureus is quantitatively analyzed by means of the electron probe spectroscopy.On the basis of comprehensive identification of these technologies,the quality evaluation of lapis micae aureus from various areas is carried out.The research result shows that the combination of rock identification and electron probe to apply on the identification of lapis micae aureus is an extremely effective and feasible method,which has the advantages of in situ and lossless.
