Scientific paper
Two samples from the main mass, and one from a field fragment, of the Jilin (H5) meteorite have been dated by the Ar-40 Ar-39 technique. He-4 and Ar release patterns from a nonirradiated sample were also determined, in order to obtain diffusion parameters. Concordant Ar-40 - Ar-39 ages of about 4.0 AE indicate that Jilin was totally degassed at that time. Model calculations suggest that the heating event, 400,000 years ago, was mode-rate and brief and occurred at the separation from the parent body. Such heating at separation could be a common phenomenon, explaining late disturbances in some isotope systems.
