TLDR
In this paper, the effect of sulfur dissolved as sulfide (S2−) in silicate melts on the activity coefficients of NiO and some other oxides of divalent cations (Ca, Cr, Mn, Fe and Co) has been determined from olivine/melt partitioning experiments at 1400°C in six melt compositions in the system CaO-MgO-Al2O3-SiO2 (CMAS), and in derivatives of these compositions at 1370°C, obtained from the six CMAS compositions by substituting Fe for MAbout:

Partitioning of platinum-group elements and Au between sulfide liquid and basalt and the origins of mantle-crust fractionation of the chalcophile elements
James E. Mungall,James M. Brenan +1 more
TL;DR: In this paper, the authors present direct experimental measurements of D PGE sul, based on in situ microanalysis of the sulfide and silicate melt, with values ranging from ∼4.5 × 105 (Ru) to ∼2.3 × 106 (Ir, Pt) and they use their new set of partition coefficients to develop a fully constrained model of PGE behavior during melting which accurately predicts the abundances of PME in mantle-derived magmas and their restites, including mid-ocean ridge basalts, continental picrites, and the parental magmas

The Temperature and Pressure Dependence of Nickel Partitioning between Olivine and Silicate Melt
TL;DR: In this article, the authors measured Ni partitioning between olivine and melt, D^(ol/liq)_(Ni), in experiments on mid-ocean ridge basalt (MORB) encapsulated in Olivine at pressures from 1 atm to 3·0 GPa and temperatures from 1400 to 1550°C.

Trace element mineral/melt partitioning for basaltic and basaltic andesitic melts: An experimental and laser ICP-MS study with application to the oxidation state of mantle source regions
TL;DR: In this article, the trace element partition coefficients for a large number of trace elements, in the various minerals present in basaltic rocks, and under diverse conditions, particularly of variable fO2.

Prediction of metal–silicate partition coefficients for siderophile elements: An update and assessment of PT conditions for metal–silicate equilibrium during accretion of the Earth
TL;DR: In this paper, the behavior of the moderately siderophile elements Ni and Co was compared using several approaches, each of which results in the same conclusion for Ni and co. The main difference between the current result and several other recent modeling efforts is that Mn, V, and Cr are hosted in deep mantle phases as well as the core.

Evaporation of moderately volatile elements from silicate melts: experiments and theory
Paolo A. Sossi,Stephan Klemme,Hugh St. C. O'Neill,Jasper Berndt,Frédéric Moynier,Frédéric Moynier +5 more
TL;DR: In this paper, a series of experiments in which silicate liquids are evaporated in one-atmosphere (1-atm) gas-mixing furnaces under controlled f O 2 s, from the Fe-“FeO” buffer (iron-wustite, IW) to air (10 -0.68 bars), bracketing the range of most magmatic rocks.
