core-mantle boundary , CMB (abbreviation)

A layer of liquid water may be present at the core-mantle boundary.

Most pallasites are believed to be derived from the core-mantle boundary.

The presence of heterogeneous features along the core-mantle boundary might have a bearing on this theory.

What is the nature and heterogeneity of the lower mantle and core-mantle boundary?

These are postulated to comprise columns of hot material that rise from the core-mantle boundary.

Seismology in particular is heavily relied upon for information about the deep mantle near the core-mantle boundary.

These and other observations have led to the obvious speculation that plumes arise at the core-mantle boundary.

The D" layer at the core-mantle boundary separates the mantle from the core.

The core-mantle boundary is a strong thermal (temperature) discontinuity.

In discussing the core-mantle boundary the two scientists avoided taking sides on whether that is where the plumes originate.

The most prominent thermal contrast known to exist in the deep ( 1000 km) mantle is at the core-mantle boundary.

There is no other known major thermal boundary layer in the deep Earth, and so the core-mantle boundary was the only candidate.

The source of mantle plumes, is postulated to be the core-mantle boundary at 3,000 km depth.

"Nobody's proved that helium-3 is from the core-mantle boundary," Dr. Anderson said in an interview.

One of the hypotheses is this is the so-called D"-layer at the core-mantle boundary.

If the ice contains enough ammonia or other antifreeze, Titania may possess a liquid ocean layer at the core-mantle boundary.

Hot mantle at the core-mantle boundary rises while cool mantle sinks, causing convection cells to form.

One suggests that they are due to hot mantle plumes that rise as thermal diapirs from the core-mantle boundary.

He also worked on determining the depth of the core-mantle boundary as well as other properties of the interior of the earth.

Slabs have been imaged down to the seismic discontinuities between the upper and lower mantle and to the core-mantle boundary.

Seismic data will also give scientists more understanding and insight into the lower mantle and the Earth's core, as well as activity at the core-mantle boundary.

Pallasites were once thought to originate at the core-mantle boundary of differentiated asteroids that were subsequently shattered through impacts.

Because there is little material transport across the core-mantle boundary, heat transfer must occur by conduction, with adiabatic gradients above and below this boundary.

However, seismic tomography rejects this hypothesis, as it shows that the plume beneath the Hawaii hotspot extends to the core-mantle boundary.
