article description
We have repeated the measurement of radiogenic 82 Kr and 130 Xe in the mineral kitkaite, NiTeSe, and obtained half-life values of (1.2 ± 0.1) × 10 20 y for 82 Se and (7.5 ± 0.3) × 10 20 y for 130 Te based on the parent/daughter ratios in the kitkaite and the xenon retention age of associated uraninite. The mineralization age of the kitkaite is used to set upper limits of T1282 ⩽ 2 × 1020y and T12130 ⩽ 12.5 × 1020y.
