华北克拉通鲁西地区沂水杂岩研究现状、问题及展望

Research Status, Problems Analysis and Prospect of the Yishui Complex in the West Shandong Area of the North China Craton

华北克拉通作为全球最老的克拉通之一,其前寒武纪结晶基底广泛记录了地球早期构造热演化的信息。位于华北克拉通东南缘鲁西地块的沂水杂岩,是华北克拉通前寒武纪结晶基底的典型代表,是我们探讨华北克拉通前寒武纪构造热演化的理想窗口。本文通过对前人研究工作总结,从沂水杂岩的原岩组成、年代学研究、地球化学特征、变质作用及其大地构造意义几个方面全面综述目前研究进展,浅析存在问题及研究展望,为进一步深入研究沂水杂岩前寒武纪构造热演化研究提供参考,进而推动华北克拉通早前寒武纪构造热演化过程以及地球早期板块构造机制的发展。

As one of the oldest cratons in the world, the Precambrian basement of the North China Craton records information on early continental evolution, attracting the attention of many early Pre-cambrian geologists at home and abroad. The Yishui Complex, located in the southeastern margin of the North China Craton, is a typical representative of the Precambrian crystalline basement of the North China Craton and an important window for us to explore the Precambrian tectonic and thermal evolution of the North China Craton. Therefore, this article will summarize and expand the controversy on the composition, age, and age of the protolith of the Yishui complex, geochemical characteristics, metamorphism, and its tectonic significance, as well as the existing issues in previous research work, and it provides a reference for further research on the Precambrian tectonic thermal evolution of the Yishui complex, and further promotes the development of the early Precambrian tectonic thermal evolution process of the North China Craton and the early plate tectonics mechanism of the Earth.
