(Urey, J Chem Soc 1947:562–581, .) predicted that different isotopes would behave slightly differently in chemical (and physical) reactions due to mass differences, leading to the conc

Radiometric Dating Applied to Ore Deposits: Theory and Methods,dented technological developments. In order to understand how metallic ore deposits form and thus construct genetic models that may serve as exploration guides, determining the age of an ore deposit is one of the most important pieces of information needed. More recently it has also become evident t

,U–Pb Dating of Mineral Deposits: From Age Constraints to Ore-Forming Processes, technical developments, innovations and investigation, the U–Pb system arguably is the most mature radioisotopic system in our possession to conduct absolute dating of a wide range of minerals across geological environments and metallogenic processes. Here, we review the basics of U–Pb geochronolog
