中国脉石英矿床类型、成矿特征及作为高纯石英矿的潜力OA

Vein quartz is a crucial natural raw material for high-purity quartz in China,and related research holds significant strategic importance for ensuring the self-reliance,controllability,and sustainable development of the high-purity quartz industry chain.Based on existing exploration results and research literature of vein quartz deposits in China,this study categorizes them into three major types:pegmatite-type,hydrothermal-type,and weathered deposits.Through systematic analysis of the metallogenic processes,ore and mineralogical characteristics of different deposit types,combined with processing and purification experimental data,it is confirmed that pegmatite-type,weathered deposits in specific regions,and metamorphic hydrothermal vein quartz deposits possess the potential to be purified into high-purity quartz.
