摘要

The analytical results of noble gas in recently fallen Juancheng chondrite indicate that cosmic-ray ages of cosmogenic nuclei of ~3He, ~21Ne and ~38Ar are 5.1, 5.0 and 5.8 Ma, re- spectively, averaging 5.3 Ma. The gas retention ages radiogenic nuclei of ~4He and ~40Ar are 3 200 and 4 200 Ma, respectively. The average cosmic-ray age shows that it has occurred at breakup of the meteoroid its parent body by impact before 5.3 Ma.
