Mn-Cr relative sensitivity Factors for Secondary Ion Mass Spectrometry analysis of Mg-Fe-Ca olivine and implications for the Mn-Cr chronology of meteorites

McKibbin, Seann; Amelin, Yuri; O’Neill, Hugh St. C.; Holden, Peter; Ireland, Trevor


Secondary Ion Mass Spectrometry (SIMS) is used to date meteoritic olivine using the 53Mn-53Cr short-lived decay scheme. This involves simultaneously measuring the Cr-isotope composition and Mn/Cr ratio of a sample, but the relative sensitivity of SIMS to
