摘要
研究区的蛇纹岩以构造就位的方式就位于具岛弧环境的白水河群变质岩系之中，其常量元素和微量元素地球化学特征表明，其原岩成分相当于蛇绿岩层序底部的变质橄榄岩，是地幔的残余。它是在岛弧与扬子古陆相互碰撞过程中形成的。
Terpentine emplaced as tectonic lens into Baishuihe group was formed in an island arc environment.Its geochemistry characteristics of main element and trace element suggest that they are similar to the metaperidotite at the bottom of ophiolite sequence, They are relict of mantle and formed during collision between island-arc and Yangtz continent。
