摘　　要：板块构造的起始和演化是固体地球科学的重要研究内容。岩石地球化学大数据分析可以较全面地用于研究全球构造体制的变化对岩浆岩、沉积岩、变质岩等记录所带来的全球性影响。板块构造样式随着地幔潜在温度的降低,会经历一系列的演化并最终在新元古代末期转变为现代样式的板块构造。板块构造的演化也显著影响着地质历史时期地幔热状态和地表-深部的物质循环,岩石地球化学大数据研究是揭示这些地质过程的重要手段。The initiation and evolution of plate tectonics is one of the fundamental issues of Solid Earth Science.Analysis of lithogeochemical big data can be comprehensively applied to study the influence of the evolution of Earth’s tectonics regime on global archives of igneous,sedimentary,and metamorphic rocks.With the decrease of mantle potential temperature,the Earth’s tectonics regime underwent a series of evolution and eventually evolved into modern-style plate tectonics at the end of the Neoproterozoic era.It is suggested that the evolution of plate tectonics also significantly affects the thermal state of the mantle and the material cycling between Earth’s surface and interior during geological time.As an important means,the research of lithogeochemical big data plays a critical role to reveal those geological processes.
