摘　　要：该研究在详述了蛇绿岩岩石组成及岩石特征后,对蛇绿岩岩石地球化学特征进行分析,结果表明:蛇绿岩岩石属钙碱性系列,富集高场强元素,稀土元素含量较低,略微富集轻稀土元素,显示岩浆来源于亏损地幔源,并有富集地幔物质的加入。The study in detail the composition and features of ophiolite rocks of ophiolite,rock geochemistry analysis,the results showed that： the ophiolite rocks belong to the calc alkaline series,enriched in high field strength elements,rare earth element content was low,slightly enriched in light rare earth elements,displayed the magma was derived from a depleted mantle source,and has the added enriched mantle material.
