Flotation of Diamond in Mantle Melt at High Pressure |

1995-7-14 · Experiments show that diamond floats in a primitive mantle melt at around 20 gigapascals and 2360°C and in a melt formed by partial melting of the transition zone at about 16 gigapascals and 2270°C. 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 ...

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 Earth's history. Thus, the transition zone could be a reservoir of diamond.

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 sink-float method using olivine and diamond as density markers. Using these data, we obtain K and K' of the Birch-Murnaghan 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 ...

Density of a FeO-rich peridotite (MA, a model composition of Martian mantle) melt was investigated by high pressure experiments conducted at 6.3–18.0 GPa and 1800–2570°C. We adopted the `sink–float' method, i.e., the sinking and flotation of a certain crystal (density marker) in the silicate melt is judged from its position in the run ...

implies that the pressure effect on the partial molar volume of water in silicate melt (dVft2o/dP) is highly dependent on pressure regime. Thus, H20 can be thought of as the most compressible 'liquid oxide' component in silicate melt at low pressure, but at high pressure its compressibility resembles that of other liquid oxide components.
