Abstract: | The tendency of iodine to be mobilised during secondary processing is reflected both in the presence of 129XeXS in secondary minerals and in the bulk 129XeXS/I ratios in meteorites. Comparison of absolute ages derived through calibration of chronometers based on 129Xe, 53Mn and 26Al against the Pb-Pb system yields a plausible timescale for the early solar system. In this system, the earliest chondrule
ages are most readily interpreted as representing formation after the beginning of parent body processing.
