早期陆壳的性质、成因及演化过程是地质学重要的研究内容。前寒武纪地质研究具有探讨早期大陆岩石圈地质演化历史及其深部地质过程无法取代的双重地位，这一领域在过去20年中一直是固体地球科学研究的热点，并成为众多国际地质对比计划的研究焦点。与世界其它古大陆（特别是北
The nature, genesis and evolution of the early continental crust are important studies in geology. The Precambrian geological study has the double status of exploring the geologic evolution history of the early continental lithosphere and its in-depth geological processes. This field has been the focus of solid earth science research for the past 20 years and has become a hot spot in many international geological contrast plans Research focus. And other ancient continents of the world (especially the north
