Apatite Reference Materials for SIMS Microanalysis of Isotopes and Trace Elements

“…A large number of apatite have been used as RM for volatile and non-volatile element mass fractions, U-Th-Pb and Lu-Hf geochronology, and isotope ratios of H, O, S, Sr, Cl, and Nd (Sano et al 1999, Amelin and Zaitsev 2002, Horstwood et al 2008, Kennedy 2011, Kennedy et al 2012, Li et al 2012, Barford et al 2005, Chew et al 2011, Marks et al 2012, Thomson et al 2012, Norman and Nemchin 2014, Yang et al 2014, Kusebauch et al 2015, Thompson et al 2016, Silva et al 2018, Doucelance et al 2020, Fisher et al 2020, Gonc ßalves et al 2020, Yang et al 2020, Hammerli et al 2021, Krestianinov et al 2021, Li et al 2021, Simpson et al 2021, Wudarska et al 2021. We have previously distributed BR2 (Grange et al 2009, Davis et al 2011, Norman and Nemchin 2014, Bellucci et al 2015 and BR5 (Gall et al 2017, Bao et al 2022, for which there is early U-Pb TIMS data, and the data presented in this article provide an update for the BR2 and BR5 apatite RM.…”
