| Abstract | A major issue in thermochronology and U-Th-Pb dating is the effect of radiation damage, created by a-recoils from alpha-decay events, on the diffusion of radiogenic elements (e.g., He and Pb) in host mineral. Up until now, thermal events have been considered as the only source of energy for the recovery of radiation-damage. However, irradiation, such as from the alpha-particle of the a-decay event, can itself induce damage recovery. Quantification of radiation-induced recovery caused by alpha-particles during alpha-decay events has not been possible, as the recovery process at the atomic-scale has been difficult to observe. Here we present details of the dynamics of the amorphous-to-crystalline transition process during a-particle irradiations using in situ transmission electron microscopy (TEM) and consecutive ion-irradiations: 1 MeV Kr2+ (simulating alpha-recoil damage), followed by 400 keV He+ (simulating a-particle annealing). Upon the He+ irradiation, partial recrystallization of the original, fully-amorphous Durango apatite was clearly evident and quantified based on the gradual appearance of new crystalline domains in TEM images and new diffraction maxima in selected area electron diffraction patterns. Thus, alpha-particle induced annealing occurs and must be considered in models of alpha-decay event damage and its effect on the diffusion of radiogenic elements in geochronology and thermochronology. |
