    摘要:

    高纯石英具有重要的战略地位,是高新技术产业的基础原材料。本文对高纯石英原料的特征和矿床成因研究方法进行了系统的归纳。通过观察石英岩相学特征,分析矿物包裹体及流体包裹体的数量、大小、化学成分、存在形式和分布状态,以及SiO2和微量杂质元素的含量和赋存状态,可以研究高纯石英原料的矿物学特征;通过ArAr同位素定年可以计算高纯石英原料矿床的成矿年龄;通过H—O同位素测试,Ti、Al、Ge、Li等微量元素含量分析,可以研究高纯石英原料矿床的成矿物质来源;通过分析流体包裹体的均一温度、盐度、化学组成等特征以及SEMCL微结构观察,可以研究高纯石英原料矿床的成矿作用过程。在此基础上,本论文对我国高纯石英行业的发展提出相关的建议。

    Abstract:

    High purity quartz has an important strategic position and is the basic raw material of high-tech industry.This paper systematically summarizes the characteristics and ore deposit genesis research methods of high purity quartz raw materials.By observing the petrographic characteristics of quartz,analyzing the quantity,size, chemical composition,existing form,distribution state of mineral inclusions and fluid inclusions,as well as the content and occurrence state of SiO2 and trace impurity elements,the mineralogical characteristics of high purity quartz can be studied;The ore-forming age of high purity raw quartz ore deposit can be calculated by Ar-Ar isotopic dating;Through the H—O isotope test and the analysis of trace elements such as Ti,Al,Ge,Li,etc.the source of ore-forming material of high-purity raw quartz ore deposits can be studied;By analyzing the homogenization temperature,salinity,chemical composition and other characteristics of fluid inclusions and SEM-CL microstructure observation,the mineralization process of high purity raw quartz ore deposit can be studied. On this basis,this paper puts forward relevant suggestions for the development of high purity quartz industry in China.
