Miocene anatexis, cooling and exhumation in the Khumbu Himal, Nepal

International Geology Review, 2021
The Khumbu region of Nepal is host to numerous large leucogranite bodies that comprise some of the most iconic peaks in the Himalaya.

Crustal anatexis: An experimental review

Tectonophysics, 1977
Review of experimental studies in synthetic systems An—Ab—Or—Qz—H_2O and K_2O—Al_2O_3—SiO_2—H_2O illustrates the dominance of feldspar—quartz assemblages in crustal anatectic processes, and the role of hydrous minerals such as muscovite. H_2O-undersaturated liquids can exist with quartz—feldspar assemblages through hundreds of degrees with little ...

A model for the origin of Himalayan anatexis and inverted metamorphism

Journal of Geophysical Research: Solid Earth, 1998
The origin of the paired granite belts and inverted metamorphic sequences of the Himalaya has generally been ascribed to development of the Main Central Thrust (MCT). Although a variety of models have been proposed that link early Miocene anatexis with inverted metamorphism, recent dating studies indicate that recrystallization of elements of the MCT ...

Some remarks on contact anatexis

Bulletin Volcanologique, 1970
The chemical variability of the products of contact-anatexis, completely different from the normal trend of magmatic differentiation, may be explained by the quantitative variation of gaseous transfer, according to the state of the basaltic magma which may be pyromagma or hypomagma at the contact with the surrounding sialic rocks.

Experimental anatexis and genesis of migmatites: A reply

Contributions to Mineralogy and Petrology, 1966
Recentlyvon Platen applied the results of his laboratory experiments to a migmatite studied byHarme. Some comments are presented upon that re-interpretation.

Contrasting behaviour of boron during crustal anatexis

Lithos, 2001
The study of volatile elements in crustal anatectic terranes may provide information about the role of fluid flow and fluid pathways during high temperature metamorphism. We have studied the distribution of Li and B in two migmatitic areas: the . Pena Negra Anatectic Complex central Spain and the migmatites and leucogranites associated with the Ronda ...

Paleogene anatexis along the Gulf of Alaska margin

Geology, 1979
Early Tertiary plutons of biotite tonalite, granodiorite, and granite are found in a curvilinear 2,000-km-long belt along the margin of the Gulf of Alaska. These plutons intrude flyschoid rocks that were accreted to the continental margin during Late Cretaceous and/or early Tertiary time.

Crustal anatexis during the influx of mantle volatiles

Lithos, 1993
Abstract Many data show that large masses of silicic magma can be formed by crustal anatexis under the influence of volatiles, possibly enriched in primary water derived from a mantle source. In the present paper, a model of crustal anatexis, accompanied by a limited influx of volatiles is suggested.

Trace element fractionation during anatexis

Geochimica et Cosmochimica Acta, 1970
Abstract The theoretical basis of trace element fractionation presented in a paper by P. W. Gast (1968) can be developed in a more flexible algebraic form, which is here described and illustrated.
