This study assesses the effect of chemical abrasion on in situ mass spectrometric isotopic and elemental analyses in zircon. Chemical abrasion improves the U–Pb systematics of SIMS (secondary ion mass spectrometry) analyses of reference zircons, wh

Baddeleyite is a powerful chronometer of mafic magmatic and meteorite impact processes. Precise and accurate U–Pb ages can be determined from single grains by isotope dilution thermal ionization mass spectrometry (ID-TIMS), but this requires disagg

Although the U-Pb zircon chronometer has been widely used for dating metamorphism in moderate to high-grade rocks, it is generally difficult to link the U-Pb age of zircon to specific metamorphic reactions. In this study, the initial Hf isotopic comp
