Study of mineral chemistry, thermobarometry and petrogenesis of migmatitic rocks of Hamedan area [PDF]
پترولوژی, 2018 In the Hamedan region, migmatitic rocks occur with various structures. In the Simin area (South Hamedan) stromatic and in the Darreh-Omar (Toyserkan) area ophtalmitic structures are abundant.

Seismic evidence for partial melt below tectonic plates [PDF]
Nature, 2020 <p>The seismic low-velocity zone (LVZ) of the upper mantle is generally associated with a low-viscosity asthenosphere that has a key role in decoupling tectonic plates from the mantle. However, the origin of the LVZ remains unclear. Some studies attribute its low seismic velocities to a small amount of partial melt of minerals in the ...

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.

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 ...

A geochemical study of the winonaites: Evidence for limited partial melting and constraints on the precursor composition [PDF]
, 2017 The winonaites are primitive achondrites which are associated with the IAB iron meteorites. Textural evidence implies heating to at least the Fe, Ni–FeS cotectic, but previous geochemical studies are ambiguous about the extent of silicate melting in ...

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 ...
