Abstract

Abstract

En 中文
• Bayesian multi-tracer inversion resolves age mixing that controls redox transitions. • Key redox transitions occur in mixing zones, not in end-member waters. • U mobilizes in young oxic recharge; As and 226Ra release in reducing pockets. • Fe(II) oxidation at interfaces attenuates the trace-elements via co-precipitation. • Microbial signatures (Geobacter) corroborate iron reduction and contaminant release.
