Re-Os isotope studies of Mindanao adakites: Implications for sources of metals and melts (2005)
Journal Article
Dreher, S., Macpherson, C., Pearson, D., & Davidson, J. (2005). Re-Os isotope studies of Mindanao adakites: Implications for sources of metals and melts. Geology, 33(12), 957-960. https://doi.org/10.1130/g21755.1

Whether the downgoing slab in modern subduction zones is able to melt is an important unresolved aspect of plate tectonics. Rare arc lavas with high Sr/Y ratios and low Y and heavy rare earth element concentrations, called adakites, are often attribu...

Sources, degassing, and contamination of CO₂, H₂O, He, Ne and Ar in basaltic glasses from Kolbeinsey Ridge, North Atlantic (2005)
Journal Article

New volatile data (CO₂, H₂O, He, Ne, and Ar) are presented for 24 submarine basaltic glasses from the Kolbeinsey Ridge, Tjörnes Fracture Zone and Mohns Ridge, North Atlantic. Low CO₂ and He contents indicate that magmas were strongly outgassed with t...

High-3He/4He, depleted mantle and low-δ18O, recycled oceanic lithosphere in the source of central Iceland magmatism (2005)
Journal Article
Macpherson, C., Hilton, D., Day, J., Lowry, D., & Gronvold, K. (2005). High-3He/4He, depleted mantle and low-δ18O, recycled oceanic lithosphere in the source of central Iceland magmatism. Earth and Planetary Science Letters, 233(3-4), 411-427. https://doi.org/10.1016/j.epsl.2005.02.037

New helium and oxygen isotope data and trace element concentrations are reported for volcanic rocks from central Iceland. Basalts that are depleted in the most incompatible trace elements possess a wide range in 3He/4He but most ratios are similar to...
