Abstract:The isotopic composition of lithium (Li) in clinopyroxene (Cpx), determined via in situ micro‐analysis, has been employed as a potential geochemical tool for studying various geological processes such as crust‐mantle recycling, silicate weathering and fluid‐rock interaction. To obtain precise and accurate Li isotopic compositions in Cpx by LA‐MC‐ICP‐MS, synthetic Cpx matrix‐matched reference materials (RMs) were prepared in this study. Six Cpx‐matrix RMs were prepared by mixing metallic oxides with GSP‐2 (gran… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
