DOI: 10.1038/s41561-020-0617-y
Abstract: Similar to Earth, many large planetesimals in the Solar System experienced planetary-scale processes such as accretion, melting and differentiation. As their cores cooled and solidified, substantial chemical fractionation occurred due to solid metal–liquid metal fractionation.… read more here.

DOI: 10.1039/c6ja00446f
Abstract: This paper presents a new method for high precision Pd isotope analyses in iron meteorites. First, Pd is separated from the sample matrix by a novel two-stage anion exchange procedure after which isotopic measurements are… read more here.
