Description:
A tomographic image of the upper mantle beneath central Tibet from INDEPTH
data has revealed a subvertical high-velocity zone from ~ 100- to ~ 400-
kilometers depth, located approximately south of the Bangong-Nujiang Suture.
We interpret this zone to be downwelling Indian mantle lithosphere. This
additional lithosphere would account for the total amount of shortening in the
Himalayas and Tibet. A consequence of this downwelling would be a deficit of
asthenosphere, which should be balanced by an upwelling counterflow, and thus
could explain the presence of warm mantle beneath north-central Tibet.
