Overburden or lithostatic pressure.
Overburden or lithostatic pressure.
The overburden load / self weight of the approximately 150 to 190 km of material that overlies the layer of the Earth's mantle where diamonds form creates the pressure required.
Diamonds are able to form in the Earthâ??s mantle. This is because there is carbon and great amounts of heat and pressure.
Gravity and the mass of rock above the diamond stability zone.
The weight of the rocks above the mantle results in high pressure.Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
Overburden or lithostatic pressure.
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
Diamonds are believed to be formed about 90 miles below the surface of the Earth, in the mantle. So, the weight of the Earth above them creates the pressure to form diamonds.
The overburden load / self weight of the approximately 150 to 190 km of material that overlies the layer of the Earth's mantle where diamonds form creates the pressure required.
Diamonds are able to form in the Earthâ??s mantle. This is because there is carbon and great amounts of heat and pressure.
Gravity and the mass of rock above the diamond stability zone.
Pressure and extreme heat.

The weight of the rocks above the mantle results in high pressure.Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
Diamonds form under great pressure and heat in the mantle. The mantle surrounds the core. Diamonds are found in intrusive lava, (underground deposits)
