Diamonds, according to the theory of Geology, are formed and then 'stored' in a very special area under the Earths surface called diamond stability zones.
This is where the special conditions of pressure/heat/energy/mineral combo is found to form diamonds.
Diamonds can not slowly make their way up to the surface or they will not remain a diamond. The theory is they are forced upwards rapidly (through volcanic kimberlites) and then remain on or just below the surface as diamonds.
A diamond has been found to contain the mineral Ringwoodite. How does a diamond contain Ringwoodite?
Ringwoodite diamond formation puzzle
- The theoretical mineral Ringwoodite is found in the Earths theoretical mantle depth of 325 miles to 410 miles.
- Bridgmanite (silicate perovskites) is a theoretical lower mantle mineral between 410 miles and 1800 miles. It is suggested it makes up about 40 percent of the whole volume of the Earth.
- Diamond stability zones are found at a depth of around 85 miles to 120 miles below the Earths surface.
Ringwoodite diamond mystery
How does a Ringwoodite diamond form and both survive?
If there is one Ringwoodite diamond then why are there not lots more?
Perhaps diamonds and the minerals Ringwoodite and Bridgmanite are formed during intense electromagnetic events?
