Identifying xenocrystic tourmaline in Himalayan leucogranites

American Mineralogist, 2023
Abstract Tourmaline is a common autocrystic mineral in granitic and pegmatitic rocks that records valuable information on the physicochemical evolution of magmas. However, xenocrystic tourmaline that does not crystallize from host magmas is also common but seldom reported and notoriously difficult to identify.

Petrochemical characteristics of leucogranite and a case study of Bengbu leucogranites

Science Bulletin, 2009
Leucogranites have a relatively narrow variation in SiO2 content (70.5%–75.5%). Giving similar SiO2 content, leucogranites have relatively higher Al2O3 (>13.5%) and lower TFeO + MgO (

Experimental Crystallization of Leucogranite Magmas

Journal of Petrology, 1995
Abstract Both crystallization and melting experiments have been carried out on two natural, biotite-muscovite (DK) and tourmaline-muscovite (GB) High Himalayan leucogranites (HHL) at 4 kbar, logfO2 = FMQ−0·5, aH2O = 1−0⋅03, and at five temperatures between 803 and 663°C H2O contents of the quenched glasses were analysed by ion ...

Two-mica and tourmaline leucogranites from the Everest-Makalu region (Nepal-Tibet). Himalayan leucogranite genesis by isobaric heating?.

Lithos, 2002
In the Higher Himalaya of the region from Cho Oyu to the Arun valley northeast of Makalu, the Miocene leucogranites are not hosted only in the upper High Himalayan Crystallines (HHC); a network of dykes also cuts the lower HHC and the Lesser Himalayan Crystallines (LHC).

Crustal generation of the Himalayan leucogranites

Tectonophysics, 1987
Abstract Detailed studies of the Himalayan two-mica leucogranites, such as the Manaslu pluton, indicate that they have very uniform mineralogical, petrological and structural characteristics. One can relate their occurrence to the thickest zones of the underlying Tibetan Slab.

Himalayan Leucogranites: Petrogenesis and Significance

Elements
Himalayan leucogranites crop out intermittently over 2000 km along the crest of the world’s youngest and largest mountain range. They are derived from partial melting of continental crust during a classic continental collisional orogeny. Studies of these leucogranites have significantly advanced knowledge of crustal anatexis, felsic magmatic ...
