Previously commented on the important key of the seismic tomography model to enhance or understand areas with kimberlites / lamproites with large diamonds and ultra deep diamonds. In the figure the focal point Juina and the data of P-T on its inclusions of super deep diamonds. Overlapping the seismic tomography model

the 1D profile, both using the excellent model TX2011 (in blue line that is compared with PREM -line in red) on a coordinate of kimberlite area of Juina (vertical line in black). On the right side the phase diagram of potential mineral inclusions in diamonds according to Shirey and Shigley (https://www.gia.edu/gems-gemology/wn13-advances-diamond-geology-shirey).If everything to be perfect, the mineralogy of the super deep diamonds of Juina (better in kimberlite than in alluvions) should be approximated to what is shown in dashed lines to the depth of under approximately 740 to 750 km of S and S basaltic or peridotitic composition. For this it is assumed that the seismic tomography suggest something of high temperatures. In the same way, super deep diamond inclusions between 450 km at 600 km depth (unlikely), according to the same reasoning, should be from a higher temperature formation environment to those commented above. It is like that?.
