四川会理小青山铜(金)矿区的钠长石英板岩主要由钠长石及石英组成。钠长石英板岩的化学成分中富SiO_2、Al_2O_3及Na_2O,贫K_2O、FeO及MgO;稀土元素特征为:ΣREE=30.13～42.11,ΣCe/ΣY=1.80～1.98,δEu=0.23～0.34,δCe=0.48～0.59。钠长石英板岩是由绢云母千枚岩及(碳质)板岩等变泥质岩经钠交代作用形成的。部分钠化的岩石中常有原岩的结构、构造及矿物的残留。区内的铜(金)矿床与钠长石英板岩的形成作用密切相关。
The albite quartzite of the Xiaoqiaoshan copper (gold) deposit in Huili County, Sichuan Province is mainly composed of albite and quartz. The chemical compositions of albite quartzite are rich in SiO_2, Al_2O_3 and Na_2O, lean K_2O, FeO and MgO. The REE characteristics are as follows: ΣREE = 30.13 ~ 42.11, ΣCe / ΣY = 1.80 ~ 1.98, δEu = 0.23 ~ 0.34, δCe = 0.48 ~ 0.59. Albite quartzite is formed by sericite phyllite and (carbonaceous) slate and other argillaceous metamorphism via sodium metasomatism. Part of the sodium-bearing rocks are often the structure of the original rock, structure and mineral residue. The copper (gold) deposits in the area are closely related to the formation of albite slate.
