K-Ar Age of Yamato Meteorite, Yamato-74190-01(L)
Preliminary measurements have been carried out on the isotopic compositions and contents of helium, neon and argon in Yamato-74190-01 (L). K-Ar age and exposure ages on the meteorite have been calculated as follows : K-Ar age (∿2.1 b. y.), exposure ages (24 and 22 m. y. in terms of ^3(He) and ^<2...
