| 摘 要： | 以微量元素、稀土元素、Ｓｒ和Ｎｄ同位素变异特征为依据，确定鲁苏榴辉岩为多成因、多来源和多阶段，指出主要是在印支期扬子陆块与华北陆块碰撞造山作用过程中，挤入的上地幔碎片以及不同原岩类型的壳内高压变质岩碎块。燕山晚期的区域构造热事件使得某些榴辉岩的同位素体系再平衡。

| Abstract: | Based on the correlation characteristics of the trace elements,rare earth elements,Sr and Nd isotopes,it is determined that the eclogites in the Lu-Su collision orogenic zone are multigenesis,multisource and multiperiod,but they are mainly the upper mantle pieces and high-pressure metamorphic rock pieces of differente protolith types diapiring in the collision orogenic process between the Yangzi Block and the Northern China Block at the Indo-Chinese epoch.The regional structurethermal event at the late of Yangshan epoch caused the isotopic system of some eclogites to reach reequilibrium. |
