Abstract

In this study, we aim to apply LA-ICP-TOF-MS mapping to CM chondrites to determine (i) the elemental abundances in the constituent minerals, (ii) the most enriched phase(s) of an element, and (iii) the elemental distribution among the constituent minerals, which may reveal the elemental re-mobilization during aqueous alteration in the parent bodies and then the environmental condition of the aqueous alteration.
