KeywordRb 高精度 分馏 精馏 地质样品 同位素组成
AbstractRb有2个天然同位素:~(85)Rb、~(87)Rb,其中~(87)Rb为放射性同位素。经典的研究认为同一时期Rb同位素比值为一个定值(~(85)Rb/~(87)Rb=2.593),由于~(87)Rb/~(85)Rb相对质量差并不小(Δm/m≈0.023),在某些地质过程中有可能存在同位素分馏。不过,目前鲜有对Rb同位素组成高精度测定的报道,对此方面的认识还基本是空白。为进一步探讨该问题,我们对前人的分析方法进行改进,在MC-ICP-MS(multi-collector inductively coupled plasma mass spec-
