Characterizing Early Solar System Fluids on the Allende (CV3) Parent Body: Nanosims Study of Phosphate Volatile Contents

Abstract

Much of our knowledge about the early Solar System comes from the study of CV3 meteorites, in particular Allende. Hydrothermal alteration is recognized as an important, ubiquitous process within these rocks (e.g. [1]). Nevertheless, we know little regarding the nature of these fluids. Volatile element abundances in phosphates from carbonaceous chondrites could constrain relative fugacities of H_2O, HF and HCl in the fluid present during metasomatism in primitive planetesimals.
