摘要
条痕状角闪混合岩与其围岩变(浅)粒岩为渐变过渡关系．并呈现一些特殊的结构构造．其岩石化学成分变化波动性较大,说明岩石化学成分不稳定,与矿化含量的不稳定性一致．其特殊的岩石化学组成显示为混合岩特征．条痕状角闪混合岩石稀土总量ΣREE的平均值为207．18×10-6;ΣCe／ΣY平均值为3．25;La／Yb为平均值为6．48,δEu平均值为0．48,Eu／Sm平均值为0．16．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．
The strip mixing amphibolite is transiting relation with its wall rock granulite,and rise special structure.The chemical contents of rock change,it shows the chemical contents isn＇t stable,The special rock chemical Content show characteristic of mixed rocks.averagy of the all qutity of the strip mixed amphibolite race earth is 207.18 ppm. averagy of ∑ce/Y is 3.25; averagy of La/Yb is 6.48; averagy of δEu is 0.48; averagy of Eu/Sm is 0.16. These Characteristic are resemble all kind of granttlite of Lieryu group,is layer shape mixing granite.
