The presence or absence of a vapour phase during incongruent-melt reactions of muscovite and biotite together with the composition of the protolith determines the trace-element characteristics of the resulting melt, provided that equilibrium melting occurs for those phases that host the tracc elements of interest. For granitic melts, Rb, Sr and Ba provide critical constraints on the conditions that prevailed during melting, whereas REE are primarily controlled by accessory phase behaviour. Mass… 
The role of fluids in the formation of High Himalayan leucogranites
Abstract During fractional melting of the crust, the availability of fluids is a critical variable that influences the melt fraction obtained, the capacity of the melt to migrate from its source and
Accessory phase controls on the geochemistry of crustal melts and restites produced during water-undersaturated partial melting
The profound geochemical conseqences of accessory phase behaviour during partial melting of highgrade metapelites are demonstrated with reference to two geochemically distinct crustal melts produced

Abstract The diverse fluid regimes during melting of the metasedimentary crust have been often discriminated on the basis of the composition of anatectic granitoids, with granites indicating
Abstract The production of S-type granites has been related to the extraction of melts during water-undersaturated melting of metasediments in the lower continental crust. If this mechanism is of
Coupling of anatectic reactions and dissolution of accessory phases and the Sr and Nd isotope systematics of anatectic melts from a metasedimentary source
Advances in field observations and experimental petrology on anatectic products have motivated us to investigate the geochemical consequences of accessory mineral dissolution and nonmodal partial
Granite: From genesis to emplacement
At low temperatures (<750 °C at moderate to high crustal pressures), the production of sufficient melt to reach the melt connectivity transition (∼7 vol%), enabling melt drainage, requires an influx
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 metal-bearing peraluminous granites such as rare metal
From sediment to granite: timescales of anatexis in the upper crust
Abstract Granite formation is the culmination of a sequence of events initiated by prograde heating of the protolith and followed by formation of a grain-boundary melt, melt segregation into a vein
REE fractionation and Nd-isotope disequilibrium during crustal anatexis: constraints from Himalayan leucogranites
Abstract The processes controlling rare earth element (REE) behaviour during crustal anatexis have profound implications not only for REE abundances of crustally derived granites but also for their
Geochemical study of processes in granulite facies migmatites from Prydz Bay, eastern Antarctica
Partial melting has been proposed as a mechanism for producing the low aH20 conditions characteristic of granulites, but the extent to which melts produced by water-undersat-urated partial melting


Trace element behaviour during migmatization. Evidence for a complex melt-residuum-fluid interaction in the St. Malo migmatitic dome (France)
The St. Malo migmatitic dome represents an interesting example wherein migmatites arise from the anatexis of the surrounding gneisses. Petrographical and chemical data suggest that leucosome
The application of trace elements to the petrogenesis of igneous rocks of granitic composition
Abstract Although trace element modeling has been used to great advantage for petrogenetic interpretations of basaltic systems, similar studies on igneous rocks of granitic composition have been
Phase equilibria and melt productivity in the pelitic system: implications for the origin of peraluminous granitoids and aluminous granulites
AbstractPeraluminous granitoid magmas are a characteristic product of ultrametamorphism leading to anatexis of aluminous metasedimentary rocks in the continental crust. The mechanisms and
Constraints on melting and magma production in the crust
Major intrusions of granitic rocks are found in several tectonic settings and, in all cases, crustal melts may contribute to the volumes of granitic magma. High-grade metamorphism and partial melting
Fluid-absent (dehydration) melting of biotite in metapelites in the early stages of crustal anatexis
Experimental investigation of the fluid absent melting reaction biotite+plagioclase+A12SiOs+quartz~ garnet + K-feldspar + melt at 10 kbar, indicated that melt- ing began between 760 and 800~ and was
The effect of accessory minerals on the redistribution of lead isotopes during crustal anatexis: A model
Abstract The initial Pb isotopic composition of anatectic granites is modelled as a mixture of Pb derived from major minerals that have characteristically low 238 U 204 Pb and 232 Th 204 Pb ratios
Zircon saturation revisited: temperature and composition effects in a variety of crustal magma types
Abstract Hydrothermal experiments in the temperature range 750–1020°C have defined the saturation behavior of zircon in crustal anatectic melts as a function of both temperature and composition. The
Experimental determination of the fluid-absent melting relations in the pelitic system
In order to provide additional constraints on models for partial melting of common metasediments, we have studied experimentally the melting of a natural metapelite under fluid-absent conditions. The
What controls partial melting in migmatites
The layers of six stromatic migmatites from Northern, Western, and Central Europe display small but systematic chemical and mineralogical differences. At least five of these migmatites do not show
Petrology and U/Pb geochronology of the Telohat migmatites, Aleksod, Central Hoggar, Algeria
The Aleksod region is composed of metasedimentary rocks and large areas of biotite and hornblende-bearing migmatites. Anatexis associated with the main deformation stages, occurred under high
