Study on the Mineralogical Characteristics of Different Types of Siliceous Materials in Some Areas of Hubei Province
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.
