山门银矿床石英含矿性的谱学找矿标志

ON THE SPECTROSCOPY ORE GUIDES FOR THE ORE GENERATING POTENTIALITY OF QUARTZ IN THE SHANMEN SILVER DEPOSIT

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。

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 Co_2H_2O;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.
