Ringwoodite, wadsleyite and ferropericlase are all found in this structure. Scientists believe that a high pressure form of magnesium silicate called post perovskite exists in part of this structure, which contains an outer region home to the asthenosphere and lithosphere. The lower layer of this region, sometimes referred to as the D double prime layer, contains an area called the Gutenberg discontinuity while the top part of this region is called the Moho discontinuity.
