The composition of the lower mantle: Evidence from mineral inclusions in diamonds

The composition of the lower mantle zones may be studied from the composition of minerals included in sub lithospheric diamonds. Multiphase mineral inclusions are rarely observed in such diamonds, and therefore, we may judge on the rock types hosting these diamonds on the basis of the chemistry of i...

Description
Summary:The composition of the lower mantle zones may be studied from the composition of minerals included in sub lithospheric diamonds. Multiphase mineral inclusions are rarely observed in such diamonds, and therefore, we may judge on the rock types hosting these diamonds on the basis of the chemistry of individual minerals.
