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.

Syntectonic crustal melting and high-grade metamorphism in a transpressional regime, Variscan Massif Central, France [PDF]
, 2009 Hot collisional orogens are characterized by abundant syn-kinematic granitic magmatism that profoundly affects their tectono-thermal evolutions. Voluminous granitic magmas, emplaced between 360 and 270 Ma, played a visibly important role in the evolution

Synchronous N-S and E-W extension at the Tibet-to-Himalaya transition in NW Bhutan [PDF]
, 2015 Despite ~50 Myr of continuous continent-continent collision, contractional structures in the Himalayan-Tibetan orogen are today limited to the northern and southern margins of the system, while extension dominates much of the interior.

The South Millevaches Middle Carboniferous crustal melting and its place in the French Variscan Belt [PDF]
, 2009 International audienceSeveral episodes of crustal melting are now well identified in the Variscan French Massif Central. Middle Devonian (ca 385-375 Ma) migmatites are recognized in the Upper and Lower Gneiss Units involved in the stack of nappes.

Textural and mineral-chemistry constraints on columbite-group minerals in the Penouta deposit: evidence from magmatic and fluid-related processes [PDF]
, 2018 The Penouta Sn-Ta deposit, in the northwest of Spain, is a greisenized granitic cupola where Ta minerals occur mainly as disseminations in a leucogranite body intruded in Precambrian–Lower Cambrian gneisses and mica-schists. This leucogranite is a medium-
