Abstract

Since both the 53Mn-53Cr system and nucleosynthetic Cr anomalies serve as tracers of early Solar System processes, this study aims to investigate small-scale Cr isotopic variabilities in CI and CI-like chondrites to gain better insights into their genetic relationship and the thermal processing experienced by their parent bodies.
