the commodity sector is electric. the purpose is to transform the pressure that is in the earth's mantle, and that at the bottom of the earth, growing up to 3 - 4 million atmospheres.using the technique of drilling for oil on the bottom of the ocean, down to 5 - 6 miles. it uses...
Little is known about the real conditions in the earth's interior because direct sampling is not feasible. The propagation of seismic waves is the only instrument for investigating the mantle. Therefore, viscosity η is of prime importance. Experimental data indicate that mantle viscosity is about ...

The mineral olivine dominates the composition of the Earth's upper mantle and hence controls its mechanical behaviour and seismic anisotropy. Experiments at high temperature and moderate pressure, and extensive data on naturally deformed mantle rocks, have led to the conclusion that olivine at upper-...
Natural diamonds were (and are) formed (thousands of million years ago) in the upper mantle of Earth in metallic melts at temperatures of 900–1,400 °C and at pressures of 5–6 GPa (refs. 1,2). Diamond is thermodynamically stable under high-pressure and high-temperature conditions...

Pressures in the hydrospheres of large ocean worlds extend to ranges exceeding those in Earth deepest oceans. In this regime, dense water ices and other high-pressure phases become thermodynamically stable and can influence planetary processes at a global scale. The presence of high-pressure ices ...
Ultramafic lenses that are relatively more intact are exposed in the eastern part of the western limb of the ISB and have been regarded as one of the oldest mantle slices exposed on Earth ⇑ Corresponding author at: School of Environmental Science and Management, University of the Philippines ...
