Relationship between radiogenic heat production in granitic rocks and emplacement age
Energy Geoscience, 2023 Granites play a crucial role in the Earth's thermal regime and its evolution. Radiogenic heat production (RHP) by the decay of radioactive elements (U, Th, K) in granites is a significant parameter in estimating the thermal structure of the lithosphere ...

Tectonic and magmatic factors of Li-F granites localization of the East of Russia
Записки Горного института, 2021 We have investigated tectonic and magmatic factors of Li-F granites localization of the East of Russia. The study is based on the ideas of Far Eastern geologists about the deep structures of intraplate activity.

The Tibet leucogranite as a potential high-purity-quartz raw material: first discovery and case study from the Dinggye area [PDF]
European Journal of MineralogyThis study evaluates Tibet leucogranites as a potential raw material for high-purity quartz. We systematically investigate the petrography, geochemistry, and purification potential of leucogranites from the Ama Drime Massif of the Dinggye area.

Neoproterozoic magmatic evolution of the southern Ouaddaï Massif (Chad)
BSGF - Earth Sciences Bulletin, 2020 This paper presents new petrological, geochemical, isotopic (Nd) and geochronological data on magmatic rocks from the poorly known southern Ouaddaï massif, located at the southern edge of the so-called Saharan metacraton. This area is made of greenschist

Interaction of B-rich supercritical magmatic fluids with granite: first report of dumortierite in Larderello, Italy [PDF]
E3S Web of Conferences, 2019 In a peraluminous two-mica monzogranite cored at 4.5 km depth in well Radicondoli 29, dumortierite occurs together with andalusite, Li-rich tourmaline, fluorite and fluorapatite.

Evidence for present-day leucogranite pluton growth in Tibet [PDF]
Geology, 2004 Several geophysical surveys carried out in southern Tibet have revealed the occurrences of bright spots of high electrical conductivity at 15–20 km depth, corresponding to zones of seismic attenuation and correlated to high heat flow at the surface.

Geodinamica Acta, 2019 Granitoids of the Ekecikdağ Igneous Association (Central Anatolia/Turkey) are products of collisional–post-collisional magmatism in the Ekecikdağ area. These granitoids are granodiorite, microgranite and leucogranite.

Granite magmatism and mantle filiation [PDF]
European Journal of MineralogyCurrent granite magma generation models essentially reduce to two groups: (1) intra-crustal melting and (2) basaltic origin. A mixed, crustal, and basaltic origin and therefore a mantle filiation has been proposed for most granite magma types.
