Figure 37.

Initial 187Os/188Os versus age, derived from 187Re-187Os isochrons for magmatic iron meteorites (IA, IVB, IVA, IIAB, IIIAB), main group pallasites (MGP) and angrites (estimated from least disturbed samples). Also shown is the field for least-disturbed chondrite compositions. Solid line shows the chondritic evolution line from the average initial 187Os/188Os of chondrites and the dashed line shows the regression through the iron meteorite initial compositions. Data sources are provided in the text and provide a Solar System 187Os/188Os initial value of 0.0952 ± 0.0002.
