摘要: 宝山-桃行榴辉岩呈透镜状包体赋存于荣成花岗质片麻岩套（Chgg）内，通过榴辉岩主量元素地球化学、微量元素及稀土元素地球化学、石榴子石矿物化学分析，确定榴辉岩原岩为壳成变质成因，具有岛弧拉斑玄武岩（IAT）特征.宝山-桃行榴辉岩是其原岩与围岩一起经过高温高压变质作用而形成.

Abstract: The Baoshan-Taoxing eclogite scatters in the granitic gneisses in the middle section of Sulu orogenic belt. With study on the major element, trace element and rare earth element geochemistry, as well as the mineral chemistry of garnet, it is concluded that the protolith of the eclogite is island arc tholeiite (IAT) derived from metamorphic crust and experienced HTP metamorphism along with its wall rock.
