Abstract
The Qiankeng Lithium Mine in Yifeng County is located at the southern edge of Jiuling Mountains.The mining area mainly exposes granite bodies that invaded at different stages of the Early Cretaceous,showing characteristics of homologous evolution.The medium to fine-grained muscovite granite(including medium to fine-grained porphyry muscovite granite)is an ore bearing rock mass,and the main elements of the medium to fine-grained muscovite granite are mainly subalkaline in the SiO2-(Na2O+K2O)discrimination map of the samples;On the A/CNK-A/NK plot,the sample mainly consists of subalkaline peraluminous regions;On the SiO2-K2O discrimination diagram,the sample belongs to the high potassium calcium alkaline series,with enriched elements Li and Cs,as well as enriched elements Rb,F,and P.It belongs to granite and exhibits characteristics of high fluorine and high phosphorus.The high degree of differentiation and evolution of magma is the main factor in forming the ore bearing parent rock-lithium rich granite.The superposition of albitization and lithium mica further enriches lithium elements.关键词
