WebJul 15, 2024 · Our data suggest that mismatched U and Pb abundances in the deposit are best accounted for by at least part of the U having been added late, as late as 1 b.y. after initial formation at ca. 1.59 Ga. The highest U ore grades (>2000 ppm U) are associated with U/Pb ≥ 10, equivalent to “chemical” U-Pb ages <0.7 Ga ( Fig. 2 ).
