| 摘 要： | 变质岩记录了地球特别是大陆形成以来的演化历史。变质作用是地球出现固态岩石后构造演化的物质记录，是地球岩石圈的黑匣子、深部探针和指示剂，是深时地质记录最典型的地质指纹。变质岩及变质作用承载了地球特别是大陆构造演化过程以及构造体制随时代演化的研究重任。随着变质相平衡研究的发展以及相关数据资料的积累，因应大数据时代的到来，如何完善变质岩岩石学知识体系，对分散的数据进行整合，形成新一代数据平台，运用大数据方法解决前沿科学问题，成为变质岩岩石学新的学科生长点。文章总结介绍了国内外与变质岩有关的数据库（如MetPetDB、PetDB等），并对近年的研究热点做了综述。笔者认为，大数据驱动下，可以针对一些相关科学问题先行开展研究，如：（1）早期大陆的物质、形成机制、生长过程和稳定化； （2）造山带、克拉通结构以及洋陆相互作用的过程；（3）壳-幔相互作用、接触带结构、能量、相转换与物质交换；（4）地球的热体制演化及其与大陆结构与成分演变的时空联系。

| Abstract: | Metamorphic rock records the Earth evolutionary history since the generation of its continental crust. Metamorphism stores information of the tectonic evolution and other geological processes from the solid rocks formed. Metamorphic rock is the focal point for the tectonic evolution study, especially when it comes to the scope of continental tectonics and tectonic regime change through time. With the development of metamorphic phase equilibrium research and the accumulation of relevant data, how to improve the knowledge system of metamorphic petrology, integrate the scattered data, form a new comprehensive data platform, and employ the big data to solve the frontier scientific questions have attained plenty of interests in metamorphic petrology. This paper summarized the databases related to metamorphic rocks, such as MetPetDB, PetDB, etc., as well as the research hotspots in recent years. As a result, big data-driven research subjects in this field were proposed as:(1) the generation, growth and stabilization of the early continental crust; (2) the process of cratonization, orogenesis, and ocean-continental interaction; (3) crust-mantle interaction and the structure, energy, phase transition and material exchange within the contact belt; (4) evolution of the Earth thermal regime and its temporal and spatial connection with the continental structure and composition change. |
