 note = {P(論文), Three fragments of the Juvinas (eucrite) taken from the main mass with a size of about 30cm were analyzed by the ^<40>Ar-^<39>Ar method in order to examine differences of secondary thermal effects. The brecciated matrix shows a scattered pattern in the ^<40>Ar-^<39>Ar age spectrum, indicating excess ^<40>Ar in the higher temperature fractions. Two other fragments show no definite plateau ages but indicate similar age patterns. A probable disturbance event (s) around 4-4.1 Ga is indicated in the 975-1050℃ fractions. Thus, Juvinas shows evidence of secondary thermal events, probably due to impacts.},
