医巫闾山变质核杂岩具有典型三层结构，是一个具有长期变形演化历史、岩浆活动强烈、结构复杂的变质核杂岩。项目主要开展构造要素几何学、运动学和动力学研究，结合同位素测年，确定其变形期次和阶段，分析其形成演化过程；同时深入研究岩浆活动特征、变形变质特点、岩石流变机制以及构造-热动力学演化历史。重点开展岩体（脉）构造、显微组构综合分析，建立判别变形不同阶段就位岩体（脉）的标志与准则; 开展岩浆成因锆石与独居石U-Pb同位素年代学分析，建立岩浆活动-构造变形的年代学格架；对于不同阶段就位花岗岩体（脉）开展部分岩石化学、地球化学、同位素地球化学分析，揭示出构造变形不同阶段岩浆活动特征，为阐明医巫闾山变质核杂岩变形不同阶段构造-岩浆活动机制和过程提供资料，进而探讨伸展变形构造活动的属性以及构造变形-岩浆作用的相互制约关系。

The Yiwulüshan metamorphic Core Complex（Ymcc）in western Liaoning Province is tectonically located in northeastern of North China Craton. It has a three-layer structure, being a long evolution of deformation, strongly magmatic activity and complex structure of metamorphic Core Complex. The project study the geometry, kinematics and dynamcs of structural elements, to research a period and stages of deformation, to analysis the process of evolution and formation, combining with isotopic dating. At the samt time ,to research characteristics of magmatic activity, the features deformation and metamorphism, the rheologic mechanism of rocks and the evolutional history of structural and thermal dynamics. The distinguish indicates of different stages of deformation are to be set up by to study the structural features of plutonic body(veins) and the combination analysis of micro-fabrics. The chronological conformation of magmatic activity and tectonic deformation will be established by analysis of U-Pb isotopic dating of magmatogenic zircon and monazite. The analysis of petrochemistry, geochemistry and isotopic geochemistry of different stages plutonic bodies(veins) will be done, to reveal magmatic characteristics of different stages. The project will provide some data for the magmatic activity mechanism and process in different deformation stages of Ymcc, to discuss property of extensional deformation and the relation between structural deformation and magmatism.
