Effects of off-axis melt supply at fast-spreading mid-ocean ridges: A study of the 9-10n region of the East Pacific Rise
… of both rise-centered and off-axis mantle melt accumulation. Here, we investigate the effects of off-axis melt accumulation on the architecture of overlying crust as well as off-axis melt delivery on crustal construction along the ridge axis. We first present evidence for off-axis magmatism …

Metamorphic and melt-migration history of midcrustal migmatitic gneisses from Nupskapa, The Maud Belt, Antarctica
Melt migration is an important process in the crust that causes significant mass transport, as well as differentiation and stabilisation of continental crust. Melt migration near the source occurs pervasively, through interconnected networks of melt-bearing structures. This style is restricted to …

Seismic Tomography at Volcanic Rift Zones and Transpressional Plate Boundaries Askja Caldera and Macquarie Island
… System (GNSS), which is consistent with shallow melt accumulation. Seismic attenuation, a sensitive indicator of partial melt, was derived from a shallow local earthquake dataset to corroborate the presence of the shallow magma reservoir. A new 3-D model of absorption reveals a shallow …
