Anatectic events and related leucogranites are rarely reported from Precambrian large igneous provinces (LIPs). However, their appearance is possible in relation to the intrusion of later pulses of mafic magmas into the earlier rocks.

The Himalayan orogenic belt is characterized by widespread leucogranites, which are mostly peraluminous with less than 5% mafic minerals. Previous studies mainly focused on the petrological characteristic, genetic mechanism, magmatic evolution and ...

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).

Himalayan Leucogranites: A Geochemical Perspective
ElementsThe geochemical characterization of Himalayan leucogranites offers important insights into both their petrogenesis and Himalayan orogenic processes. Himalayan leucogranites are characterized by strongly peraluminous compositions that are comparable to melts derived from anatexis of sedimentary rocks.

Petrogenesis of leucogranites in collisional orogens
Geological Society, London, Special Publications, 2019Abstract Leucogranites are a characteristic feature of collisional orogens. Their generation is intimately related to crustal thickening and the active deformation and metamorphism of metapelites. Data from Proterozoic to present day orogenic belts show that collisional leucogranites (CLGs) are peraluminous, with muscovite ...

The Himalayan leucogranites, which were derived from crustal anatexis during the India-Asia continental collision, have recorded the tectono-magmatic evolution process of the Himalayan orogenic belt.

Himalayan Leucogranites: Petrogenesis and Significance
ElementsHimalayan 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 ...

JURASSIC LEUCOGRANITE-GRANITE FORMATION IN ALTAI
Russian Geology and Geophysics, 1991A Middle-Mesozoic (Jurassic) leucogranite-granite formation, 180–200 Ma of age, has been recognized in Rudny and Gorny Altai on the basis of U–Pb geochronological dating, analysis of petrochemical data and metallogenic characteristics. In adjacent geostructural environments, granitoid massifs differ in completeness of manifestation of granite and ...

Lithogeochemical exploration for uranium in leucogranites
Journal of Geochemical Exploration, 1989Abstract In certain leucogranitic massifs in France and Spain, anomalies of uranium that extend for kilometers have been observed in rocks close to uranium deposits. Some of these anomalies were used to direct a reconnaissance survey which led to the discovery of a small blind deposit.
