The Dabieshan area in China is characterized by the widespread occurrences of Mesozoic metamorphism and magmatism, with abundant vein quartz resources, which may become one of the key regions for strategic mineral exploration of high-purity quartz (raw material) in China. This paper determines the quality grades of high-purity quartz vein quartz samples from the Hongjiawan mineral occurrence and Baishishan deposits in the Dabieshan area. A comparative analysis is conducted based on factors such as hand specimens, fluid inclusions, content and occurrence states of impurity element in the ores with different quality grades, to identify typical quality evaluation indicators for vein-quartz ores in the Dabieshan area. The content of SiO2 in the processed quartz sand from Hongjiawan and Baishishan vein-quartz ores can reach 99.9971% and 99.9968% respectively, which meets the quality requirements of middle and high-end products. The quality of the Hongjiawan ore is better than that of the Baishishan ore. The comparative study of different quality of high purity quartz raw materials shows that, if the vein quartz is snow-white in color, higher transparency, larger fluid inclusion sizes dominated by two-phase (liquid-vapor) primary fluid inclusions, and lower impurity elements content, the quartz has the greater probability of becoming high purity quartz raw materials. The contents of impurity elements in recrystallized quartz and core of quartz veins are generally low, thus we should pay more attention to this part of quartz. This conclusion has a significance for evaluating the potential resources of high purity quartz raw materials in this area and clarifying the geological characteristics of future prospecting targets.
