The Ural mobile belt is an intracontinental epioceanic orogen that has already gone through all stages of the geodynamic development. Igneous rocks formed during each stage are important indicators for understanding the evolution of this belt and ...

Fe-Ti oxide minerals can be locally aggregated or enriched in the quartzofeldspathic gneisses from the Larsemann Hills, East Antarctica. The enrichment is related to anatexis and subsequent high-grade metamorphism, not inherited from the protolith.

New monazite U-Pb age constraints on the evolution of the Paleoproterozoic Vaasa granitoid batholith, western Finland [PDF]
The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny.

Formation mechanism of the Vaasa Batholith in the Fennoscandian shield: Petrographic and geochemical constraints [PDF]
The ~1.88 Ga Vaasa Batholith in western Finland is a large granitoid area (8 000 km2) with gradational contacts against the garnet- and cordierite-bearing diatexite and metatexite migmatites of the Pohjanmaa Belt.

Eastern margin of the Vaasa Migmatite Complex, Kauhava, western Finland: preliminary petrography and geochemistry of the diatexites [PDF]
Extensive biotite diatexites resembling S-type granitoids occur in the eastern part of the Vaasa Migmatite Complex (VMC, 1.89 Ga, 6000 km2) at Kauhava, western Finland.

Experimental Constraints on Himalayan Anatexis [PDF]
We have melted metapelitic rocks from the High Himalayan Crystalline Sequence that are likely sources of leucogranite magmas. Starting materials were a muscovite schist and a tourmaline-bearing muscovite–biotite schist. Both are kyanite-zone rocks from the hanging wall of the Main Central Thrust.

Trace and Rare-Earth element geochemical study of twenty samples of migmatitic banded gneisses, garnet biotite schists, dolerites, granites and rhyolites was carried out in a bid to determine their petrogenetic and tectonic significance in the evolution

Archean (about 2500 Ma) anatexis in eastern North China Block
Two Neoarchean alkaline feldspar-rich granites sourced from partially melted granulite-facies granodioritic orthogneiss have been here recognised in the eastern part of the North China Block (NCB).

Fluid-induced metamorphism and anatexis of refractory Ni-Co-Cu sulphides in subduction-related rocks [PDF]
The role of metamorphism on refractory sulfides is not well constrained. Although experiments have displayed the effectiveness of high grade metamorphism, namely granulite facies metamorphism, on sulfide anatexis, its role in the presence of other ...
