大陆岩石圈厚度控制着地球构造模式、克拉通稳定性和矿产资源分布,但其演化历史长期缺乏有效研究手段。传统地球物理观测方法难以追溯古老岩石圈厚度变化,而现代板内玄武岩作为古老岩石圈熔融的典型产物,依然缺少利用其来反演地球早期岩石圈厚度及演化规律的方法和认识。

    大陆岩石圈厚度控制着地球构造模式、克拉通稳定性和矿产资源分布,但其演化历史长期缺乏有效研究手段。传统地球物理观测方法难以追溯古老岩石圈厚度变化,而现代板内玄武岩作为古老岩石圈熔融的典型产物,依然缺少利用其来反演地球早期岩石圈厚度及演化规律的方法和认识。

    中国科学院海洋研究所孙卫东团队基于全球51522组玄武岩地球化学数据,通过大数据分析,创新性建立玄武岩熔融深度定量反演方法。采用移动平均法和蒙特卡洛模拟分析,首次揭示22亿年前与陆内玄武岩喷发有关的岩石圈增厚现象:熔融压力从小于2.5 GPa跃升至大于3 GPa,对应岩浆源区石榴石残留比例从小于5% 剧增至大于20%。地幔的持续冷却和休伦期冰川的融化可能促使地球构造样式在22亿年前左右从间歇式俯冲转变为持续式俯冲。稳定的俯冲作用推动了Nuna超大陆(也称为哥伦比亚超大陆,是地球历史上最早形成的超大陆之一)的聚合,从而引起全球大陆岩石圈板块的水平挤压和垂向增厚。
    该成果为追溯前寒武纪岩石圈厚度和演化提供了全新地球化学估算和示踪方法,为板块构造启动时间、超大陆旋回机制等提供了新的证据,为理解地球早期热体制演变和克拉通的持续稳定提供了理论支撑。
