Schematic cartoons showing the evolution of the subducted northern edge of the Indian continent. (IMAGE)
Caption
(a) Subduction of the reconstructed northern part of the Indian plate during the late Eocene. (b) A piece of subducted Indian lithosphere was detached and then sank into the MTZ seen as fast-velocity anomaly 1 (F1), as another piece of subducted lithosphere F2 continued exerting slab pull. The detachment of the slab patch has initiated the rifting process in southern Tibet shown as the two brown strips in the cartoon. (c) The subducted Indian lithosphere F2 detached and sank into the MTZ. Its detachment was accompanied by ultrapotassic volcanism and continuation of the rifting process. (d) Present distribution of the fast-velocity anomalies in the MTZ. Picture credit: Xiaofeng Liang and Yang Chu.
