Frontiers in Earth Science, 2020 Leucosome sizes in migmatites has been shown to follow power-law distribution, which is indicative of self-organized criticality governing accumulation and transport of partial melts in anatexis.

A Highly Depleted and Subduction‐Modified Mantle Beneath the Slow‐Spreading Mohns Ridge
Geochemistry, Geophysics, Geosystems, 2022 The Mohns Ridge is a very slow‐spreading ridge that, together with the Knipovich Ridge, marks the boundary between the North American and Eurasian plates in the Norwegian‐Greenland Sea.

Partial melting in the deepest mantle [PDF]
Geophysical Research Letters, 2002 We have compared the travel times of direct (P, S) and core‐reflected (PcP, ScS) phases recorded in southern Africa from earthquakes occurring in the Scotia Arc region. The low‐velocity region beneath the south Atlantic is explored by calculating ScS‐S and PcP‐P travel‐time residuals to determine the correlation and magnitude of Vs and Vp reductions in

Does Underthrusting Crust Feed Magmatic Flare‐Ups in Continental Arcs?
Geochemistry, Geophysics, Geosystems, 2020 Episodic magmatic flare‐ups are documented in many continental arcs worldwide. Yet, the causes of such episodicity and the sources feeding the flare‐ups are not well‐understood.

Nature Communications, 2017 Mantle partial melting produced the volcanic crust of Mercury. Here, the authors numerically model the formation of post-impact melt sheets and find that mantle convection was weak at around 3.7–3.8 Ga and that the melt sheets of Caloris and Rembrandt ...

Phlogopite-Olivine Nephelinites Erupted During Early Stage Rifting, North Tanzanian Divergence
Frontiers in Earth Science, 2020 The North Tanzanian Divergence (NTD, eastern branch of the East African Rift) corresponds to an early stage of continental breakup. In the southern NTD, two quaternary volcanoes of the Manyara-Balangida rift (Labait, Kwaraha) have erupted primary ...
