Q and mantle creep

Q and mantle creep

EXPERIMENTS on model materials show that the acoustic properties of the low velocity zone (LVZ) can arise from the formation of intergranular fluid or melt with no significant reduction in creep strength. Consequently, only very limited bounds on the asthenosphere can be inferred from seismic data.
