Asthenospheric low-velocity zone consistent with globally prevalent partial melting
The asthenosphere plays a fundamental role in present-day plate tectonics as its low viscosity controls how convection in the mantle below it is...

Geochemical modeling of the mantle partial melting using heuristic exploration: an optimization model applied to earth sciences
An evolution strategy-type heuristic simulation tool was developed to model the inverse problem of partial melting. The complexity of such a problem...

Peritectic orthopyroxene entrainment during partial melting of garnet peridotite produced the Bushveld Complex chromite deposits
One of the largest chromium deposits on Earth occurs in the Rustenburg Layered Suite (RLS) of the Bushveld Complex as laterally continuous chromitite...

Twinning and partial melting as early weakening processes in plagioclase at high pressure: insights from Holsnøy (Scandinavian Caledonides, Norway)
Eclogitization reactions of plagioclase-bearing rocks in water-limited environments are often incomplete. In such domains, metamorphism and strain...

Partial Melting of Plagioclase-Free Garnet–Two-Mica Metapelite As a Model of the Formation of Ultra-Potassic Felsic Magmas under Conditions of the Continental Crust
AbstractTo study the formation of S-type ultra-potassic granitic melts under the conditions of the continental crust, we conducted experiments on...

Zircon and monazite reveal late Cambrian/early Ordovician partial melting of the Central Seve Nappe Complex, Scandinavian Caledonides
The Seve Nappe Complex (SNC) comprises continental rocks of Baltica that were subducted and exhumed during the Caledonian orogeny prior to collision...

An Experimental Study of Partial Melting of Metafelsic Rocks: Constraints on the Feature of Anatectic Melts and the Origin of Garnets in Collisional Orogens
Crustal anatexis in continental subduction zones has great bearing on chemical differentiation of the continental crust at convergent plate...

Partial Melting of Carbonate–Biotite Gneiss at the Conditions of the Continental Crust: Experimental and Thermodynamic Modeling
AbstractOne of the mechanisms explaining relationships between CO 2 -rich fluids and granitoid magmas at high-temperature crustal metamorphism is the...

Evidence of Mineral Melting in Ores of the Svetlinsk Gold Deposit, South Urals, Russia
AbstractThe evidences of partial melting of minerals and the possible involvement of polymetallic melts in the accumulation and redistribution of...

Daly Gaps at South Sister, Oregon, USA, generated via partial melting
We conducted a detailed petrologic study on six crystal-poor (< 12 vol%) dacites from South Sister volcano (OR) to determine the conditions that...

Rare elements enrichment in crustal peraluminous magmas: insights from partial melting experiments
Experiments were conducted to explore the behavior of Li, Rb, Nb, Sn, Cs, Ta, W during crustal melting and test the anatectic origin of rare...

Forsterite-Anorthite-Silica: Incongruent Melting in a Ternary System
In the ternary system Di-An-Ab, we saw that the complete solid solution of plagioclase had a dominant influence on the course of liquids in the...

Kyanite petrogenesis in migmatites: resolving melting and metamorphic signatures
Aluminosilicates (kyanite, sillimanite and andalusite) are useful pressure–temperature (P–T) indicators that can form in a range of rock types...

Trace elements in abyssal peridotite olivine record melting, thermal evolution, and melt refertilization in the oceanic upper mantle
Trace element concentrations in abyssal peridotite olivine provide insights into the formation and evolution of the oceanic lithosphere. We present...

Melting geodynamics reveals a subduction origin for the Purang ophiolite, Tibet, China
The debate regarding whether the Yarlung–Zangbo ophiolite (YZO) on the south of the Qinghai-Tibet Plateau, formed in a mid-ocean ridge (MOR) or a...

Decoupling between Oxygen and Radiogenic Isotopes: Evidence for Generation of Juvenile Continental Crust by Partial Melting of Subducted Oceanic Crust
There is increasing evidence indicating that melts derived from subducted oceanic crust and sediments may have played a key role in building...
