Zinc isotopic systematics of Kamchatka-Aleutian arc magmas controlled by mantle melting

Geochimica et Cosmochimica Acta, 2018
Geochemical characteristics of arc magmas reflect incorporation of subducted materials to their mantle wedge sources in subduction zones. Subduction component addition has been proposed to modify the Zn isotopic budget of arc magmas. However, the lack of

Molybdenum and boron isotope evidence for fluid-fluxed melting of intraplate upper mantle beneath the eastern North China Craton

Earth and Planetary Science Letters, 2019
Fluid-fluxed melting of the mantle is the principal mechanism for the generation of arc magmas above subduction zones, but it has rarely been documented as important in intraplate settings.

Structure of melt flow channels in the mantle

Geotectonics, 2008
Structural events during the formation of the mantle peridotite section in the Voikar-Syn’ya massif of the Polar Urals are considered. The structural units of the mantle section were formed during several deformation stages. Dunite bodies in restitic peridotites were formed in the course of deformation that completed the formation of large-scale folds ...

Transcrystalline Melt Migration and Earth's Mantle

Science, 2006
Plate tectonics and volcanism involve the formation, migration, and interaction of magma and gas. Experiments show that melt inclusions subjected to a thermal gradient migrate through olivine crystals, under the kinetic control of crystal-melt interface mechanisms.

Melt pathways in the mantle

Nature, 1995
OCEANIC ridges are the dominant sites of energy and mass transfer from the Earth's interior to the crust, hydrosphere and atmosphere, but many key processes beneath ridges remain poorly understood. One outstanding problem is how partial melts in the asthenosphere concentrate into channels - initially, melts must leave their source by intergranular ...

Mantle Melting Mechanisms

Science, 2007
GEOCHEMISTRY During Earth's history, heavy metals gradually decoupled from silicate rocks and sank toward the core, which became differentiated from the overlying mantle. Signatures of this process can be traced in the distribution of highly siderophile elements (Re and the platinum group elements Os, Ir, Ru, Pt, and Pd) that are chemically associated ...
