Differential Evolution and Lithium Mineralization Process of Kumusayi Pegmatite in Ruoqiang County—Constraints from Mineralogy
The research area is located between the Qilian Kunlun orogenic belt,the Qaidam and Tarim blocks,in the middle section of the Altun Mountains.The main ore mineral of the Kumusayi granite pegmatite type lithium polymetal-lic deposit in Ruoqiang County is spodumene,containing tourmaline and niobium iron group minerals.After petrological and mineralogical research,it is believed that the Kumusayi pegmatite is the final product of the differentiation and evo-lution of granite magma,indicating that related minerals such as lithium bearing white mica are effective indicators of the degree of differentiation in the formation process of pegmatite.
