Xihuashan Tungsten Mine, Dayu
This is one of the most important tungsten mines in China. It is located in the mountainous area 9 km northwest of Dayu County in the vicinity of North Dayuling Mountain on the Jiangxi-Guangdong boundary. It contains a quartz vein-type ore that is closely related to the Yanshanian Xihuashan complex granite mass. The Dangping tungsten/beryllium quarry and the Xihuashan, Niuzishi, Xialuoshan, Shenglongkou, and Luokeng tungsten quarries are in the southern area of the mine, which contains a high concentration of tungsten. The largest vein of the mine, the No. 299 Tungsten Vein in the northern district, is 920 m long and up to 3.6 m wide. According to the Dayu County Chronicle, tin miners arrived in this area no later than the Song Dynasty. In 1907, the German missionary Wilhelm discovered tungsten, which was the earliest discovery and mining of tungsten in China.
