Key Points

  • This study aims to evaluate useful yields and matrix effects for SIMS-based Al-Mg dating.
  • Analyzed secondary ion mass spectrometry conditions
  • Assessed relative sensitivity factor (RSF) behavior
  • Evaluated ion matrix effects (IMF)
  • Identified optimal analytical conditions for Al-Mg dating
  • Demonstrated the importance of RSF and IMF in accurate measurements
  • Provided insights applicable to other isotopic systems analyzed by SIMS

Abstract

Our results highlight the necessity of carefully evaluating useful yields, along with the behaviors of RSF and IMF, when optimizing analytical conditions for SIMS-based 26Al-26Mg dating, as well as for other isotopic systems that can be analyzed using SIMS.
