Core Viewpoint - The article discusses the characteristics, distribution, and mining potential of vein quartz resources in China, highlighting the geological features, types of deposits, and regional resource distribution. Group 1: Resource Overview - China has identified a total of 608 vein quartz mining sites with an estimated resource volume of approximately 4.1 billion tons, primarily used for glass and metallurgy, with some regions utilizing it as a silica component in cement [2][3]. - The vein quartz deposits are characterized by small to medium-sized mining sites, with a concentration in regions such as Jiangxi, Fujian, and Xinjiang, while Qinghai and Jiangxi have the highest resource volumes [11][12]. Group 2: Geological Features - The formation of vein quartz deposits spans from the Archean to the Cenozoic eras, primarily influenced by tectonic and magmatic activities, with fractures and structural slip surfaces being the main locations for mineralization [5][9]. - The types of vein quartz deposits include magmatic hydrothermal and metamorphic hydrothermal types, with the former being predominant [9]. Group 3: Mining Districts and Characteristics - The article categorizes various mining districts based on geological and mineralization characteristics, detailing specific deposits and their silica content [15][16]. - Notable mining districts include the Altai region, with a silica content of 97.5% and a confirmed resource volume of 427.3 million tons, and the Ili microplate, with silica content ranging from 96.17% to 98.19% and a resource volume of 283.98 million tons [19]. Group 4: Regional Distribution - The distribution of vein quartz resources varies significantly across different provinces, with Jiangxi having the highest resource volume of approximately 4735.46 million tons, followed by Fujian and Xinjiang [13][14]. - The article provides a detailed map of resource distribution, indicating that the majority of mining sites are small to medium-sized, with a total of 176 small, 77 medium, and 19 large deposits identified [11][13].
