Laboratory experiments at 200 MPa show that hydrothermal tourmaline begins forming when fluid B₂O₃ exceeds ...

The oxygen fugacity (fO 2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity, and ...

Granitoids are classified into magnetite-series and ilmenite-series, and the former have higher oxygen fugacity than the latter. Magmatic oxygen fugacity is a key factor in controlling the ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...
