Abstract

The concentrations of ¹²⁹I incorporated in iodyrite (AgI) and marshite (CuI) are determined by measurements of radiogenic ¹²⁹Xe. In addition to radiogenic ¹²⁹Xe, some of these iodine-rich minerals contain excesses of ¹²⁸Xe, ¹²⁶Xe and ¹²⁴Xe which are assigned to (n, γβ^-), (n, 2nβ^-) and spallation reactions on ¹²⁷I, respectively. The concentrations of radiogenic ¹²⁹Xe indicate that the initial isotopic composition of iodine in iodyrite was (1.48±0.33)10^-14 ≤ ¹²⁹I¹²⁷I ≤ (9.8±2.2)10^-14 and in marshite it was (0.32±0.24)10^-14 ≤ ¹²⁹I¹²⁷I.
