【摘要】 石英是原生银矿床银的主要载体矿物。通过对山门银矿床石英的红外光谱、热释发光、X射线衍射、原子吸收光谱及电镜能谱等分析测定,研究了石英的含银性与包裹体CO_2和H_2O的相对吸光度间,含银性与石英热发光曲线、晶胞参数及杂质含量间关系,给出了石英含矿性的谱学找矿标志。

【Abstract】 Quartz in main silver carrier mineral of primary silver deposit. Through the analysisand determination of infrared spectrum,thermoluminescence,X-ray-diffraction(XRD),atomicabsorption as well as electron microscope spectrum of quartz in the Shanmen silver deposit,the relation between the argentiferous ratio of quartz and relative light absorbability of inclu-sion Co2H2O;the relationship between argentiferotis ratio and thermoltuminescence curves aswell as that between unit cell parameters and impurity contents were discussed. Meanwhile,ore guides on spectralogy for ore bearing quartzs are proposed.
