The Diversity of Igneous Processes in Planetesimals and Implications for the Distribution of Alkali Elements in the Early Solar System

Kurzfassung

chondrite meteorites are highly variable in composition: some are ultramafic (primitive achondrites), basaltic (e.g., eucrites and angrites), or (trachy-) andesitic (e.g., GRA 06128, NWA 11119 and Erg Chech 002). These different groups correspond to the mantle and crust of planetary building blocks, respectively. They represent a unique opportunity to constrain the early melting processes that affected planetesimals and could have influenced the final composition of planets.
