Significant boron isotopic fractionation in the magmatic evolution of Himalayan leucogranite recorded in multiple generations of tourmaline

, 2021
The late-stage evolution of leucogranite magmas and related magmatic-hydrothermal processes which could lead to rare-metal mineralization are still poorly studied in the Himalayas.

A model involving amphibolite lower crust melting and subsequent melt extraction for leucogranite generation

GSA Bulletin, 2021
In the southern Tibetan Plateau, leucogranites are dominantly distributed in the Himalayan orogenic belt with minor occurrences in the southern Lhasa subterrane. In this paper, we report the first Miocene Anglonggangri leucogranites in the northern Lhasa

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.

Spodumene pegmatites from the Pusila pluton in the higher Himalaya, South Tibet: Lithium mineralization in a highly fractionated leucogranite batholith

, 2020
The Himalayan leucogranite belt is evaluated as a prospect for rare-metal mineralization. The Pusila pluton is located 44 km northwest of Mount Everest, and consists of two-mica granite, muscovite granite, albite granite, and pegmatites.
