The oxidation state of europium as an indicator of oxygen fugacity
Geochimica et Cosmochimica Acta, 1975Empirical oxygen barometers based on Eu(2+)/Eu(3+) ratios in plagioclase feldspar and magmatic liquid were developed using Philpott's (1970) approach and the experimental data of Drake (1972). Oxygen fugacities calculated on the basis of Eu(2+)/Eu(3+) ratios for terrestrial basalts cluster tightly around 10 to the negative seventh power.

Oxygen buffering of Kilauea volcanic gases and the oxygen fugacity of Kilauea basalt
Geochimica et Cosmochimica Acta, 1993Volcanic gases collected during episode 1 of the Puu Oo eruption along the east rift zone of Kilauea Volcano, Hawaii, have uniform C-O-H-S-Cl-F compositions that are sharply depleted in CO2. The CO2-poor gases are typical of Type II volcanic gases (gerlach and Graeber, 1985) and were emitted from evolved magma stored for a prolonged period of time in ...

Recent advances in the theory and technology of solid electrolyte sensors have opened up a very promising field of direct monitoring of thermodynamic behavior of a chemical system which involves a non-condensed phase directly or indirectly. At present only oxygen and sulfur sensors are practical to use, but it is very likely that sensors for other ...
