锂云母是锂的重要工业矿物之一,可分为贫铯锂云母,正常锂云母和富铯锂云母。锂云母一般为紫色、玫瑰色,而呈白色者少见。秦东伟晶岩中的银白色锂云母为富含铷、铯的锂云母。秦岭东段是稀有金属花岗伟晶岩密集区,区内出露伟晶岩约数千条。根据稀有元素共 Lithium micaceous is one of the important industrial minerals of lithium, can be divided into levocene lepidolite, normal lepidolite and cesium-rich lithium-mica. Lithium mica is generally purple, rose, while the white is rare. Qin Dong Wei Jingyan silver white lepidolite is rich in rubidium, cesium lithium mica. The eastern part of the Qinling Mountains is a rare metal granite pegmatite-intensive area, the area exposed pegmatite about thousands. According to the rare element of total
