A wetland that received mine water discharge. Radiogenic lead exceeds 50% of total lead in the contaminated cores; it stays in place while uranium has been redistributed by redox cycling, making it a memory of the contamination.

| 50 / 350 | Cores C2, C4 and C6; core C4, at the outlet of the discharge circuit, reaches about 100 to 350. Core C1, uncontaminated, stays at the average crustal lead level. | Gourgiotis et al. (2020), New Insights into Pb Isotope Fingerprinting of U-Mine Material … |
