a Hf isotope contour map of the southern and central Lhasa terranes between of 84˚E and 94˚E showing the regional distribution of zircon εHf (t) values as measured from Mesozoic-Cenozoic granitoids and felsic volcanic rocks. b Inset figure represents plots of zircon εHf (t) values versus U-Pb age of zircons from felsic rocks. (Supplementary Dataset S2 lists literature sources for these values). c Comparison of the deep seismic reflection structures and the electrical structure by27 (see Fig. 3a for survey line location). d The electrical conductance values (in siemens (S)) calculated at depths ranging between 30–60 km by studies of Xue et al.28. e Three hypotheses proposed accounting for lateral heterogeneity in crustal-scale seismic-reflectivity patterns beneath the Lhasa terrane and the third style is the preferred model. See abbreviations in Fig. 1.
