Flotation of diamond in mantle melt at high pressure

Experiments show that diamond floats in a primitive mantle melt at around 20 gigapascals and 2360 degrees C and in a melt formed by partial melting of the transition zone at about 16 gigapascals and 2270 degrees C. These observations constrain magma densities at high pressure. Diamond precipitated o

Flotation of olivine and diamond in mantle melt at high

The density of the three ultramafic melts, PHN1611, IT8720, and MA at high pressure was determined by the sinkfloat method using olivine and diamond as density markers. Using these data, we obtain K and K of the BirchMurnaghan equation of state for the compression curves of the silicate melts. The density relation between the mantle minerals and the partial melt provides a possible

Flotation of diamond in mantle melt at high pressure

These observations constrain magma densities at high pressure. Diamond precipitated or trapped in a silicate melt at the base of the transition zone or the lower mantle floats and has been accumulating in the transition zone since early in Earths history. Thus, the transition zone could be a reservoir of diamond.

Density of hydrous silicate melt at the conditions of

2005111Here we present data constraining the density of hydrous silicate melt at the conditions of approximately 410 km depth. We show that the water in the silicate melt is more compressible than the other components, and therefore the effect of water in reducing melt density is markedly diminished under highpressure conditions.
