Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.
