Information about the upper mantle of the Earth: Internal structure studies, Material composition, Natural Phenomena. ... Earth's upper mantle is a highly viscous layer, with a capacity up to 600 kilometers, which lies between the crust and lower mantle of the Earth.

Figure 10h-2: Structure of the Earth's crust and top most layer of the upper mantle. The lithosphere consists of the oceanic crust, continental crust, and uppermost mantle. Beneath the lithosphere is the asthenosphere.

On the left, the depth and the division of the Earth after Bullen (1940) is shown. On the right hand side, the possible phase transitions within the upper mantle minerals are displayed. The discontinuities are marked by letters and numbers as described in the text.

Seismological observations have revealed the existence of low-velocity and high-attenuation zones above the discontinuity at 410 km depth, at the base of the Earth's upper mantle1, 2. It has been suggested that a small amount of melt could be responsible for such anomalies3, 4, 5. The density of silicate melt under...

The boundary between the Earth's crust and the underlying upper mantle is now recognised by a significant increase in the velocity of seismic P-waves at depths between 15 and 50 km depth. This velocity increase indicates a major change in the composition of the rocks at that boundary.

Parts of this data have been re-processed, addressing questions concerning signal penetration and lower crustal/upper mantle reflectivity, as strong lower crustal reflectivity is often absent on land data from the Baltic Shield.
