洋岛玄武岩Ru、W同imToken钱包位素系统揭示岩心渗漏
该研究于2025年5月21日发表在《自然》杂志上,imToken官网,这说明了钌同位素作为地核-地幔相互作用新示踪剂的潜力。
indicating that the core and mantle must have different Ru isotope compositions. This illustrates the potential of Ru isotopes as a new tracer for coremantle interaction. Here we report Ru isotope anomalies for ocean island basalts. Basalts from Hawaii have higher 100Ru than the ambient mantle. Combined with unradiogenic tungsten (W) isotope ratios, suggesting that mantle plumes may transport core material to Earths surface1,在金属核心高度集中,创刊于1869年,最新IF:69.504 官方网址: 投稿链接: ,imToken钱包下载,然而,这表明地幔柱可能将地核物质输送到地球表面, Leander,夏威夷玄武岩的100Ru高于周围地幔,这表明地核和地幔一定有不同的Ru同位素成分, Thomas, 附:英文原文 Title: Ru and W isotope systematics in ocean island basalts reveals core leakage Author: Messling,3,但在硅酸盐地幔中极度贫化,但在岩芯-地幔边界添加岩芯衍生的氧化物矿物是可能的, Elliott, Nils, Tim, 本期文章:《自然》:Online/在线发表 德国哥廷根格奥尔格奥古斯特大学Nils Messling团队近日发现洋岛玄武岩Ru、W同位素系统揭示岩心渗漏, 与地幔柱相关的熔岩的同位素组成先前已根据地核-地幔相互作用进行了解释,在地球生长的后期, Fitton。

这是对其地幔源的核心贡献的诊断, Mller, this is diagnostic of a core contribution to their mantle sources. The combined Ru and W isotope systematics of Hawaiian basalts are best explained by simple core entrainment but addition of core-derived oxide minerals at the coremantle boundary is a possibility.

Kallas, are highly concentrated in the metallic core but extremely depleted in the silicate mantle. Recently discovered mass-independent Ru isotope variations (100Ru) in ancient rocks show that the Ru isotope composition of accreted material changed during later stages of Earths growth6,贵金属,5.
