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 ...

Experimental modeling of diamond dissolution in kimberlite within crustal cumulative centers

Записки Горного института
The main stages within the chemically active history of diamond genesis are proposed, from the upper-mantle chambers to the explosive ejections of diamonds and kimberlite material from cumulative centers to the surface. The paper focuses on the pre-final
