Abstract

Abstract:

Chromium isotope compositions have been widely applied in cosmochemistry field, as a new approaches to date and trace the early history of the evolution of the solar system. With the development of the analytic technique, the subtle variation of Cr isotopic compositions in extraterrestrial materials can be determined. This advantage give us a new chance to re-understand and re-evaluate the genetic model of Cr and its distribution in the solar system.

Key words: Cr isotopic anomaly, analytical method, meteorites, cosmochemistry, application
