Miocene high-temperature leucogranite magmatism in the Himalayan orogen
GSA Bulletin, 2020AbstractHimalayan leucogranites of Cenozoic age are generally attributed to partial melting of metasedimentary rocks at low temperatures of <770 °C. It is unknown what the spatial distribution and characteristics of high-temperature (>800 °C) leucogranites are in the Himalayan orogen.

The Canadian Mineralogist, 2012
Spatial relations and bulk chemical compositions of three bodies of multiphase leucogranites and two categories of granitic pegmatites in the Archean Red Cross Lake greenstone belt, Sachigo Subprovince of the Superior Province in the Canadian Shield, indicate a comagmatic origin and an enormous range of fractionation.

Magnetic properties of the High Himalayan leucogranites: Structural implications
Earth and Planetary Science Letters, 1994The magnetic properties of the High Himalayan leucogranites have been investigated on 527 specimens in three plutons, Everest-Makalu (6 sites) and Manaslu (40 sites) in Nepal, and Gangotri (43 sites) in India. Susceptibility varies between 2 and 100 × 10 -6 SI, with an anisotropy ratio up to 1.16.

Lanthanide tetrad effect observ ed in leucogranites from China.
GEOCHEMICAL JOURNAL, 1989Some leucogranites from China have been found to display the tetrad effect (Masuda et al., 1987). Abundances of all rare earth elements (REE) in leucogranites from Hunan Province, China, were studied for the first time by inductively coupled plasma mass spectrometry (ICP-MS) in order to investigate the shape of the tetrad effect.

Leucogranite from Srednja Rijeka (Moslavacka Gora, Croatia)
2007The Mt. Moslavacka Gora represents crystalline crust exposed over an area of 180 km2 in the southwestern part of the Pannonian Basin. It consists of a S-type granitoid pluton surrounded by migmatites and metamorphic rocks of amphibolite to granulite facies grade.

The Isotopic Characterization of Aqueous and Leucogranitic Crustal Fluids
1989The H- and O-isotope characteristics of the principal water types - sea, meteoric, formation, organic, metamorphic, magmatic and hydrothermal-are outlined. Sea and meteoric surface waters can be involved with deep crustal processes following their downward penetration, or by their upward infiltration after oceanic or continental subduction processes ...

Himalayan leucogranites and migmatites: nature, timing and duration of anatexis
Journal of Metamorphic Geology, 2016AbstractWidespread anatexis was a regional response to the evolution of the Himalayan‐Tibetan Orogen that occurred some 30 Ma after collision between Asia and India. This paper reviews the nature, timing, duration and conditions of anatexis and leucogranite formation in the Greater Himalayan Sequence (GHS), and compares them to contemporaneous granites
