Rayleigh fractionation equation
WebThe Rayleigh isotopic fractionation model (Rayleigh 1896; Broecker and Oversby 1971) can be used as the best approximation for fluid related graphitization. Isotopic fractiona-tion during graphite precipitation by reduction of a CO 2 source can be quantified using a single component Rayleigh process, according to which the d13C of the WebApr 12, 2024 · 1 Introduction. Lithium isotope fractionation has been extensively used to investigate Earth surface processes such as water-rock interaction (Chan et al., 2002) and continental weathering (Pistiner & Henderson, 2003; Rudnick et al., 2004; Vigier et al., 2009; von Strandmann et al., 2024).The large mass difference (∼17%) between 6 Li and 7 Li and …
