Trace element partitioning within Mesosiderite clasts

Abstract

Mesosiderites are polymict silicate and metal breccias resulting from magmatic differentiation, brecciation, metal-silicate mixing, and metamorphic recrystallization in early planetary bodies. Petrographic and trace element studies have documented the great diversity of differentiated silicates, with eucritic basalt, gabbroic cumulate and diogenite clasts and trace element disequilibrium between phases (1-4).
