Short summary
Laser-based dating of rocks and minerals is invaluable in geoscience. This study significantly advances our ability to model and correct for a process called down-hole fractionation (DHF) that impacts the accuracy and uncertainty of dates. We develop an algorithm that quantitatively models DHF patterns but can be used on other geoscientific data. The implications are far-reaching: improved accuracy, reduced uncertainty, and easier comparisons between different samples and laboratories.
