Applications of Lead Isotopes to Ore Geology, Metallogenesis and Exploration

open access: yes, 2023
AbstractAlthough lead isotopes are most commonly used to date geological events, including mineralizing events, they also can provide information on many aspects of metallogeny and can be directly used in mineral exploration. Lead isotope data are generally reported as ratios of radiogenic isotopes normalized to the non-radiogenic isotope204Pb (e.g ...
