Immiscible hydrous Fe–Ca–P melt and the origin of iron oxide-apatite ore deposits
Nature Communications, 2018 The origin of iron oxide-apatite deposits remains enigmatic and controversial. Here, the authors perform experiments on intermediate magmas and show that increasing aH2O and fO2 enlarges the two-liquid field thus allowing the Fe–Ca–P melt to separate ...

A geochemical study of the winonaites: Evidence for limited partial melting and constraints on the precursor composition [PDF]
, 2017 The winonaites are primitive achondrites which are associated with the IAB iron meteorites. Textural evidence implies heating to at least the Fe, Ni–FeS cotectic, but previous geochemical studies are ambiguous about the extent of silicate melting in ...
