中国科学院青藏高原研究所的科研团队近日发表了一项关于地球深部地幔锂同位素的研究成果。该所碰撞隆升及影响团队史仁灯研究员与合作者通过系统分析青藏高原地幔橄榄岩中的锂含量和锂同位素组成，揭示了海水中锂扩散作用等地表过程对地球深部地幔锂同位素的影响。
这项研究使用矿物原位锂同位素分析方法，深入探讨了地球深部地幔锂同位素的变重现象。研究发现，地表过程如海水中锂的扩散作用对地球深部地幔锂同位素的分布和变化有着重要影响。这一发现有助于我们更好地理解地球深部地幔的物质组成和演化过程。
Title: New Tibetan Plateau Research Unveils Mysteries of Deep Earth’s Lithium Isotopes
Keywords: Tibetan Plateau, Deep Earth, Lithium Isotopes
News content:
A research team from the Tibetan Plateau Institute of Science and Technology recently published a study on the deep Earth’s mantle lithium isotopes. The team, led by Dr. Shengdeng Shi and collaborators, systematically analyzed the lithium content and isotopic composition in the mantle peridotites of the Tibetan Plateau. The study reveals the impact of surface processes such as lithium diffusion in seawater on the deep Earth’s mantle lithium isotopes.
This research employed the in-situ lithium isotope analysis method to delve into the phenomenon of lithium isotopes becoming heavier in the deep Earth’s mantle. The study found that surface processes, such as the diffusion of lithium in seawater, have a significant influence on the distribution and variation of deep Earth’s mantle lithium isotopes. This discovery helps us better understand the material composition and evolutionary process of the deep Earth’s mantle.
