Early solar system chronology

A much greater understanding for the early history of solar system has developed with the improvements in radiometric dating techniques for extraterrestrial materials. However, we still need to pursue chronological researches with a better precision to elucidate the mechanism of planetary formation and differentiation in collaboration with theoretical studies. In our laboratory, we are specifically focusing on the radiometric dating methods of 87Rb-86Sr, 146,147Sm-142,143Nd, and Pb-Pb.
