Abstract: Abstract As a siderophile and a volatile element, sulfur's partitioning behavior allows constraints to be placed on processes in the primitive Earth. Sulfur's core–mantle distribution during Earth's accretion has consequences for core content and implications… read more here.

Abstract: We present 275 new metal-silicate partition coefficients for P, S, V, Cr, Mn, Co, Ni, Ge, Mo, and W obtained at moderate P (1.5 GPa) and high T (1683–1883 K). We investigate the effect of silicate melt… read more here.

DOI: 10.1016/j.gca.2018.04.032
Abstract: Abstract Zinc is a moderately volatile and slightly siderophile element, and therefore provides information into the timing and conditions of volatile element delivery to Earth as well as the redistribution of these elements during planetary… read more here.

DOI: 10.1029/2019gl084254
Abstract: The partitioning of carbon between the core and mantle during the formation of terrestrial planets may have controlled the distribution of carbon in terrestrial planets. However, the abundance of carbon in the Earth's mantle is… read more here.

DOI: 10.1038/s41467-021-23137-5
Abstract: Highly siderophile elements (HSE), including platinum, provide powerful geochemical tools for studying planet formation. Late accretion of chondritic components to Earth after core formation has been invoked as the main source of mantle HSE. However,… read more here.

Pressure, sulfur, and metal-silicate partitioning: The effect of sulfur species on the parameterization of experimental results

DOI: 10.2138/am-2018-6282
Abstract: Abstract Performing well-controlled metal-silicate partitioning experiments at conditions directly simulating those of a deep magma ocean is difficult. It is therefore common to perform experiments at lower pressures and temperatures, which are used to determine… read more here.
