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.

On the geodynamics of the Alpine collisional granitoids from Central Anatolia: petrology, age and isotopic characteristics of the granitoids of the Ekecikdağ Igneous Association (Aksaray/Turkey)

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 Mineralogy
Current 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.

Structure of late Variscan Millevaches leucogranite massif in the French Massif Central: AMS and gravity modelling results [PDF]

, 2006
In the Limousin area, Variscan leucogranitic plutons are spatially associated with normal faults and major strike-slip shear zones that are a continuation of the South Armorican shear zone. Our study focuses on the large N-S-trending Millevaches granitic
