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 ...
