High-purity quartz is widely used in high-tech industries such as semiconductors, photovoltaics, optical communication, and light sources. It plays an important role in national strategic emerging industries, economic security, and national defense security, and is a scarce resource in the world and China. Vein quartz is one of the ideal raw materials for processing high-purity quartz raw materials. Based on extensive collection and research of vein quartz exploration results, this article divides the mineralization zones of vein quartz deposits in China according to their tectonic environment, distribution characteristics, mineralization characteristics, and controlling factors, and briefly describes the mineralization characteristics of each mineralization zone; Summarized the ore-forming laws of vein quartz deposits in China. The main types of vein quartz deposits are magmatic hydrothermal vein type, followed by metamorphic hydrothermal vein type, and pegmatite vein type. The main mineralization periods are Yanshanian, followed by the Hualixi, Caledonian, Jinning, and Indosinian periods. 27 vein quartz mineralization zones have been preliminarily divided, and it is proposed that 5 vein quartz mineralization zones, including the Lüliang, South Qinling, Tongbai-Dabie, East China Sea-Ganyu, and Altai blocks, are important high-purity quartz vein quartz mineralization zones in China. The summary of the mineralization rules of vein quartz and the division of mineralization zones provides a theoretical basis for the exploration and deployment of vein quartz.
