摘　　要：湖北是硅质原料种类较多、分布范围较广的省份,不同成因类型硅质原料矿物学特征差异明显。分别对大别山区蕲春县九棵松灵虬山脉石英、鄂西远安县旧县镇石桥村石英砂岩、鄂西宜昌夷陵殷家坪石英岩、鄂西北襄阳谷城柳榆沟石英岩等不同矿区、不同成因类型硅质原料矿石的岩石矿物组分、包裹体特征、杂质元素分布及赋存状态等矿物学特征进行研究,结果显示,产于鄂东大别山区蕲春县九棵松灵虬山脉石英岩石矿物几乎全由石英组成;视域内未见矿物包裹体,流体包裹体类型简单,以气液双相和单一液相为主;Al、Fe、Ca、Mg等十多项金属杂质元素含量之和小于0.04%,为高品质硅质原料。远安旧县石英砂岩矿物组分相对较多,但以石英为主,品位约97%;少量流体包裹体以液相为主;主要杂质元素Al、Fe含量分别为0.051%、0.027%,符合平板玻璃用硅质原料要求。柳榆沟石英岩矿物组分相对较为简单,石英以隐晶和细晶为主,未见明显包裹体;晶体细腻,质地致密坚硬;可作硅微粉及化工用原料。殷家坪石英岩杂质矿物组分复杂,杂质元素含量高,主要杂质元素总含量达6.01%以上,石英品位相对较低,其应用领域受到限制。Hubei province is a province with many kinds and wide distribution of siliceous raw materials.The mineralogical characteristics of different genetic types of siliceous raw materials are obviously different.Different silicon materials were collected including the vein quartz from Lingqiu mountain,Jiukesong village,Qichun county;the quartz sandstone from Shiqiao village,Jiuxian county,Yuan'an county;the quartz rocks from Yinjiaping village,Yiling District,Yichang;and the quartz rocks from Liuyugou village,Gucheng county,Xiangyang.The mineralogical characteristics of the rocks,such as mineral composition,inclusion characteristics,distribution and occurrence of impurity elements,are also studied.The results show,the mineral components in vien quartz rocks of Lingqiu mountain are almost all quartz;there are no mineral inclusions in the visual field,and the fluid inclusions are simple;the sum of the contents of Al,Fe,Ca and Mg is less than 0.04%,which is high quality silicon material.The mineral composition of quartz sandstone in Yuan'an Jiuxian county is relatively more,but quartz is the main one,the grade is about 97%;a few fluid inclusions are mainly liquid phase;the contents of Al and Fe are 0.051%and 0.027%,which meet the requirements of silicon materials for plate glass.The mineral composition of the quartz in Liuyugou is relatively simple,and the quartz is mainly aphanitic and no obvious inclusions,fine crystals with dense and hard texture;which can be used as silicon powder and chemical raw materials.The composition of the impurity minerals in the quartzite from Yingjiaping is complex and the content of the impurity elements is high,the total content of the main impurity elements is over 6.01%,its application is limited.
