摘　　要：混合岩与含硼岩系整合接触。并呈现条痕状构造。,成岩的常量元素的氧化物含量变化范围较大,其岩石化学成分的不稳定,与硼矿化的不稳定性相一致。Rb、Zn、La、Li、Nb、Pb、Cd、Ga、B、Be、Cs、Ta的含量混合岩与含硼岩系的变粒岩、浅粒岩非常相近。这些特点与里尔峪组的各种变(浅)粒岩相似,是层状混合花岗岩。Migmatite and boron-contained rocks are closely connected to be belt-shaped with unstable chemical elements,which is identical to the unstable condition of boron mineralization.As to content of Rb,Zn,La,Li,b,Pb,Cd,Ga,B,Be,Cs,and Ta,migmatite is similar to leptynite and leptite in boron-contained.The above feature is similar to those rocks in Li＇eryu Group.
