37 Ar and 39 Ar were measured in a bulk sample and in metal‐rich and metal‐poor fractions of the Dhajala meteorite and in metal‐rich and metal‐poor fractions of the Canon City meteorite. Two determinations of the activities in Dhajala metal phase are the following: 37 Ar = 18.9 ± 1.1 and 17.2 ± 1.2, and 39 Ar = 23.3 ± 0.9 and 24.2 ± 1.4 dpm/kg metal. In Canon City, the determinations are 37 Ar = 18.2 ± 1.4 and 16.9 ± 7.5, and 39 Ar = 18.2 ± 0.7 and 24.1 ± 1.4 dpm/kg metal. Dhajala and Canon City are of interest because they both fell during solar minimum.
