Аннотация:Receiver functions for the central Tien Shan and
northern Tarim in central Asia reveal a pronounced depression
on the 410 km discontinuity beneath the Permian basalts
in Tarim. The depression may be caused by elevated temperature.
The striking spatial correlation between the anomaly
of the MTZ and the Permian basalts suggests that both may
be effects of the same plume. This relation can be reconciled
with the possible motion of Tarim on the order of 1000 km by
assuming that the mantle layer, which has moved coherently
with the plate since the Permian, extends to a depth of 410 km
or more. Alternatively, the lithosphere and underlying mantle
are decoupled at a depth of about 200 km, but a cumulative
effect of the Tarim plate motion since the Permian is less by
an order of magnitude. A similar explanation is applicable to
the Siberian traps.
