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.

Data for: Crustal melting in a protracted hot setting in the Altai Orogen (NW China): Evidence from Permian leucogranite dykes in the metamorphic belt [PDF]
, 2021 In this contribution, we provide integrated petrological, geochronological and geochemical results of the leucogranite dykes to decipher their ages and petrogenesis and thus provide new constraints on the tectono-thermal setting of the Chinese Altai ...
