Research Abstract

In this study, the chronological study combined with petrology and isotopology were applied to the first solid material (refractory inclusions and chondrules) from primitive chodrite in the solar system which formed at first several million years on the 4.6 billion years ago. High precision Mg isotope measurements have been performed to determine the individual minerals of radiogenic ^<26>Mg in coarse-grained Ca-Al-rich inclusions (CAIs) by secondary ion mass spectrometry. Minerals in each CAI show individual mineral isochrones of ^<26>Al-^<26>Mg with respect to each own oxygen isotopic composition of minerals. This indicates that the chronological resetting event by multiple heating in the solar nebula are estimated by ^<26>Al-^<26>Mg system.
