Short summary
Decay of U to Pb in baddeleyite is used for dating mafic rocks, but some daughter Pb atoms can be ejected out of the crystal, resulting in ages that seem too young. Atom probe tomography was used to map U and Pb atoms in 3D within baddeleyite crystals and estimate the average distance that Pb atoms are displaced by recoil. This allows us to test the relationship between crystal size and apparent age. There is also evidence for clustering of U atoms, inviting more work on how this may occur.
