我们研究的主要是α——石英,其方法是KBr压片法。矿物的形成温度不同影响红外吸收谱带的变化,很早已引起人们的注意。如对不同温度形成的石英同质多形变体(鳞石英、方英石、石英、柯石英等)的研究资料已有大量报道,但在红外吸收谱带的位置和强度上的差异,且很少有研究资料。作者在工作中对这一研究课题作了一些初步的试尝。我们选择了六个不同类型热液矿床的不同成矿温度的石英,对其进行了化学和光谱分析,确定样品中石英的SiO_2的成分是纯净的,仅含微量的Al、K、Na等杂质,这些杂质可能系固态或液态的包体所引起,对红外吸收谱带的影响不大。
Our study is mainly α - quartz, the method is KBr tabletting method. The formation of different temperatures affect the infrared absorption band changes, has long attracted people’s attention. There have been a lot of research reports on the polymorphs of quartz homogeneously formed at different temperatures (tridymite, cristobalite, quartz, coesite, etc.), but there are few differences in the position and intensity of infrared absorption bands research material. The author made some tentative attempts on this research topic in his work. We chose six different types of hydrothermal deposits of different metallogenic temperature of quartz, its chemical and spectral analysis to determine the composition of quartz silica sample is pure, only trace amounts of Al, K, Na and other impurities , These impurities may be solid or liquid inclusions caused by infrared absorption band has little effect.
