By crushing olivine and pyroxene phenocrysts in volcanic rocks from Kyushu Island, Japan, we determined 3He/4He of 3–7 Ra and 40Ar/36Ar of up to 1750. These values are lower than those of MORB. 4He/40Ar⁎ (down to 0.1) is ...
The pressure-volume-temperature equation of state (EOS) of gold is fundamental to high-pressure science because of its widespread use as an internal pressure standard. In particular, the EOS of gold has been used in recent ...
