滇西某地区的稀有金属矿点产于花岗质混合伟晶岩脉中,同时伴生有较多的锡石。其成因和区域变质混合岩化、花岗岩化作用有关。它的发现为在云南西部变质岩发育地区找锡和稀有金属矿床提供了新途径。
Rare metal deposits in a certain area of western Yunnan are produced in the granitic and pegmatitic veins, accompanied by more cassiterite. The causes are related to the metamorphism of mixed metamorphism and granitization. Its discovery provides a new way to find tin and rare metal deposits in the metamorphic rock areas of western Yunnan.
