以华北克拉通南缘早前寒武纪变质杂岩体太华群和登封群中的典型岩石 (片麻岩、角闪岩) 及其相关岩石 (变闪长岩、麻粒岩、花岗岩、片岩) 为研究对象，采用年代学、岩石学和地球化学示踪相结合的方法，系统地建立起该区早前寒武纪岩浆活动的年代学框架，厘定华北克拉通南缘早前寒武纪地壳的时空演化规律。考察晚太古代至古元古代期间华北克拉通南缘的岩浆活动机制、地壳物质组成和变质作用的变化特征，并与全球早前寒武纪构造演化体系进行对比分析，揭示出华北克拉通南缘早前寒武纪构造-岩浆体系的地球动力学背景及其随时间变化的规律，验证华北克拉通中部造山带的性质，为深入理解华北克拉通早前寒武纪大陆岩石圈演化过程及其在全球性构造活动过程中的位置提供有用信息。

Geochronologic, petrologic and geochemical investigations will be carried out on the typical rocks (i.e. gneisses, amphibolite) and the related rocks (i.e. meta-diorite, granulite, granite and schist) from the Early Precambrian metamorphic complexes (The Taihua Group and Dengfeng Group) in the southern North China Craton, with aims of establishing chronology framework of the Early Precambrian magmatism and revealing the temporal and spatial evolution of the continental crust in the area. We will investigate the magmatic genesis, continental crustal components and metamorphism in the southern North China Craton during the Late Archean and Early Paleoproterozoic. By comparison with the global tectonic evolution in the early Precambrian, the studies would reveal the geodynamic and evolution of the Early Precambrian tectonic and the related magmatism in the southern North China Craton. The models of both Central Orogenic Belt and Trans-North China Orogen will also be tested in the southern North China Craton based on the new results. The data will be integrated to reveal the nature of the Early Precambrian continental lithospheric evolution of North China Craton, and to promote our understanding of its roles in the global tectonic activity.
