| 英文摘要 | The short-lived radionuclide aluminium-26 (Al-26) isotope is amajor heat source for early planetary melting. The aluminium-26 - magnesium-26 (Al-26-Mg-26) decay system also serves as a high-resolution relative chronometer. In both cases, however, it is critical to establish whether 26Al was homogeneously or heterogeneously distributed throughout the solar nebula. Here we report a precise lead-207 - lead-206 (Pb-207-Pb-206) isotopic age of 4565.56 +/- 0.12 million years (Ma) for the andesitic achondrite Erg Chech 002. Our analysis, in conjunction with published Al-26-Mg-26 data, reveals that the initial Al-26/Al-27 in the source material of this achondrite was notably higher than in various other well-preserved and precisely dated achondrites. Here we demonstrate that the current data clearly indicate spatial heterogeneity of 26Al by a factor of 3-4 in the precursor molecular cloud or the protoplanetary disk of the Solar System, likely associated with the late infall of stellar materials with freshly synthesized radionuclides. |
