Arc-like magmas generated by mélange-peridotite interaction in the mantle wedge
Nature Communications, 2018 The mechanisms of transfer of crustal material from the subducting slab to the overlying mantle wedge are still debated. Mélange rocks, formed by mixing of sediments, oceanic crust, and ultramafics along the slab-mantle interface, are predicted to ascend

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]
, 2004 The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron
