The timing of formation of the Earth’s continental crust is the subject of a long-standing debate, with models ranging from early formation with little subsequent growth, to pulsed growth, to steadily increasing growth. But most models do agree that... Read More about Helium isotopic evidence for episodic mantle melting and crustal growth.

Helium solubility in olivine and implications for high ³He/⁴He in ocean island basalts (2005)
Journal Article
Parman, S., Kurz, M., Hart, S., & Grove, T. (2005). Helium solubility in olivine and implications for high ³He/⁴He in ocean island basalts. Nature, 437, 1140-1143. https://doi.org/10.1038/nature04215

High 3He/4He ratios found in ocean island basalts are the main evidence for the existence of an undegassed mantle reservoir1, 2, 3. However, models of helium isotope evolution depend critically on the chemical behaviour of helium during mantle meltin...

Harzburgite melting with and without H₂O: Experimental data and predictive modeling (2004)
Journal Article

The effect of H2O on harzburgite-saturated melts has been quantified with a series of hydrous and anhydrous melting experiments using a piston-cylinder device. Experimental conditions were 1.2–2.2 GPa and 1175–1500°C. Melt H2O contents range from 0 t... Read More about Harzburgite melting with and without H₂O: Experimental data and predictive modeling.

The role of an H₂O-rich fluid component in the generation of primitive basaltic andesites and andesites from the Mt. Shasta region, N California (2002)
Journal Article
Grove, T., Parman, S., Bowring, S., Price, R., & Baker, M. (2002). The role of an H₂O-rich fluid component in the generation of primitive basaltic andesites and andesites from the Mt. Shasta region, N California. Contributions to Mineralogy and Petrology, 142(4), 375-396. https://doi.org/10.1007/s004100100299

This paper presents analyses of the trace element abundances and isotopic compositions in primitive lavas from the Mt. Shasta region, N California. These data are combined with estimates of pre-eruptive H2O contents and constraints from experimental...
