| 中文摘要: |
| 本文以《中国矿产地质志·贵州卷》项目为依托，对贵州硅质原料类矿产的种类、矿床类型及地质特征、找矿方向进行了系统分析研究。重点认为:贵州硅质原料类矿产的种类主要有石英砂岩，其次有粉石英和脉石英。主要矿床类型包括机械沉积型矿床(石英砂岩，细分为河湖沉积矿床和滨海沉积矿床两个亚类)、风化型矿床(粉石英)、浅成中—低温热液型矿床(脉石英)，它们的成矿作用及含矿地质体、分布区域、矿床地质特征等各不相同。从而，先后从矿种、含矿地层及沉积相、工业用途、地理—交通—环保等角度进行了找矿方向概略分析，可供该类矿产的区域找矿工作参考。 |

| Based on ‘Geology of Mineral Resources of China Guizhou Volume，’in this paper，it systematically analyzes and studies the types of mineral，the types of deposit，geological features and prospecting direction of siliceous raw material minerals in Guizhou provinceThe key point is that the types of siliceous raw material minerals in Guizhou mainly include quartz sandstone，followed by tripoli and vein quartzThe main types of deposits include mechanical sedimentary deposits (quartz sandstone，include river-lake sedimentary deposits and coastal sedimentary deposits)，weathering deposits (tripoli)，and epithermal deposit (vein quartz)，with different mineralization processes，ore bearing geological bodies，distribution regions，and geological characteristics of the depositsThus，an analysis on the prospecting direction was conducted from the perspectives of mineral types，ore bearing strata，sedimentary facies and industrial uses，geography transportation environmental protection，which can serve as a reference for regional prospecting work of this type of mineral |
