TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.
