五、研究成果及奖励        

主要研究成果：

（1）发现了俯冲带元素地球化学行为不仅受控于俯冲板块的简单变质脱水，还受到元素赋存矿物的影响，修正了对岛弧岩浆富集特征成因的传统认识。（2）揭示了俯冲带复杂的流体活动和水-岩相互作用、去碳酸盐化的直接证据和对碳循环的意义。（3）证明了同碰撞花岗岩来源于俯冲洋壳部分熔融，提出俯冲洋壳的成分多样性和其所决定的矿物结晶分异是决定可否形成埃达克质岩石的关键。（4）重新制约了上地壳平均成分。

获得奖励：

入选中国科学院海洋研究所“优秀青年”计划、中国科学院海洋研究所“汇泉青年学者”、中国科学院沈阳分院优秀青年科技人才奖、山东省泰山学者青年专家。
