On the location of plumes and lateral movement of thermochemical structures with high bulk modulus in the 3-D compressible mantle [PDF]
, 2011 The two large low shear velocity provinces (LLSVPs) at the base of the lower mantle are prominent features in all shear wave tomography models. Various lines of evidence suggest that the LLSVPs are thermochemical and are stable on the order of hundreds ...
