Experimental evidence supports mantle partial melting in the asthenosphere. [PDF]
Sci Adv, 2016 Based on sound velocity measurements, upper mantle seismic anomalies could be explained by a melt fraction as low as 0.2%.

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts
Frontiers in Earth Science, 2018 Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.

An observational and thermodynamic investigation of carbonate partial melting [PDF]
Earth and Planetary Science Letters, 2014 Abstract Melting experiments available in the literature show that carbonates and pelites melt at similar conditions in the crust. While partial melting of pelitic rocks is common and well-documented, reports of partial melting in carbonates are rare and ambiguous, mainly because of intensive recrystallization and the resulting lack of criteria for ...

Archean continental crust formed by magma hybridization and voluminous partial melting. [PDF]
Sci Rep, 2021 Archean (4.0–2.5 Ga) tonalite–trondhjemite–granodiorite (TTG) terranes represent fragments of Earth’s first continents that formed via high-grade metamorphism and partial melting of hydrated basaltic crust. While a range of geodynamic regimes can explain

An experimental study of partial melting and fractional crystallization on the HED parent body [PDF]
Meteoritics and Planetary Science, volume 50, issue 11, 1912-1924,
November 2015, 2015 We have performed an experimental and modeling study of the partial melting behavior of the HED parent body and of the fractional crystallization of liquids derived from its mantle. We estimated the mantle composition by assuming chondritic ratios of refractory lithophile elements, adjusting the Mg# and core size to match the density and moment of ...

Partial melting of deeply subducted eclogite from the Sulu orogen in China. [PDF]
Nat Commun, 2014 We report partial melting of an ultrahigh pressure eclogite in the Mesozoic Sulu orogen, China. Eclogitic migmatite shows successive stages of initial intragranular and grain boundary melt droplets, which grow into a three-dimensional interconnected ...

Mineralogical Evidence for Partial Melting and Melt-Rock Interaction Processes in the Mantle Peridotites of Edessa Ophiolite (North Greece) [PDF]
Minerals, 2019 The Edessa ophiolite complex of northern Greece consists of remnants of oceanic lithosphere emplaced during the Upper Jurassic-Lower Cretaceous onto the Palaeozoic-Mesozoic continental margin of Eurasia.

Geology, 2021 Most tungsten (W) and tin (Sn) deposits are associated with highly evolved granites derived from the anatexis of metasedimentary rocks. They are commonly separated in both space and time, and in the rare cases where the W and Sn mineralization are part ...
