Summary

New high-precision ⁵³Mn-⁵³Cr data obtained for chondrules extracted from a primitive ordinary chondrite, Chainpur (LL3.4), define an initial ⁵³Mn/⁵⁵Mn ratio of (5.1 ± 1.6) x 10⁻⁶. As a result of this downward revision from an earlier higher value of (9.4 ± 1.7) x 10⁻⁶ for the same meteorite (Nyquist et al. 2001), together with an assessment of recent literature, we show that a consistent chronology with other chronometers such as the ²⁶Al-²⁶Mg and ²°⁷Pb-²°⁶Pb systems emerges in the early Solar System.
