Flotation of Diamond in Mantle Melt at High Pressure Science

Jul 14, 1995 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

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 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

Flotation of olivine and diamond in mantle melt at high

The density relation between diamond, the mantle minerals, and the melt suggests a possibility for accumulation of diamond in the transition zone. Recent discovery of the high-pressure minerals as inclusions in diamond may be consistent with the present model of accumulation of diamond in the deep mantle.

Determining the composition of high-pressure mantle

Jul 01, 1994 Abstract. We present a new experimental technique for circumventing the quenching problems that have plagued high-pressure peridotite melting studies. A thin layer of ~50 μm diamonds is placed above a layer of peridotite powder. Partial melt extracted from the peridotite layer collects in the pore spaces between the diamonds and equilibrates

Recent Advances in Understanding the Geology of Diamonds

The significance of this for diamond formation is that the bottom 100 km of the mantle keel under each old continental crustal region is at high enough pressure and comparatively low temperature to allow diamonds to crystallize whenever they receive fluids saturated in carbon from the underlying convecting mantle.

Density and thermal expansion of a peridotite melt at high

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
