Melting of MORB at core–mantle boundary

Earth and Planetary Science Letters, 2015
Abstract We investigated the melting properties of natural mid-ocean ridge basalt (MORB) up to core–mantle boundary (CMB) pressures using laser-heated diamond anvil cell. Textural and chemical characterizations of quenched samples were performed by analytical transmission electron microscopy.

The Core-Mantle Boundary

Scientific American Sp, 1993
The largest compositional discontinuity within the Earth is the core-mantle boundary (CMB), at a depth of 2889 km. This boundary and the adjacent transition zones in the lowermost mantle and outermost core play a critical role in the Earth's thermal and chemical evolution.

The core‐mantle boundary region

Journal of Geophysical Research: Solid Earth, 1995
The 75 year history of the American Geophysical Union has accompanied great advances in our understanding of the physics and chemistry of the transition zone between the Earth's core and mantle. The core‐mantle boundary (CMB) is the most significant internal boundary within our planet, buried at remote depths and probably forever hidden from direct ...

Exploring the core-mantle boundary

Physics World, 1996
About 4.5 billion years ago, the Earth formed when rocky objects of various sizes that were spinning around the forming Sun collided and began to aggregate. As the planet grew larger, gravity caused denser compounds to move towards its centre and lighter ones towards the surface.
