Diamonds are formed under very specific conditions that need materials displaying carbon to be exposed to high pressure though low temperature (relative to many areas deep in the earth.) the temperature no less than 1652 degrees Fahrenheit and The pressure must be somewhere at least 45 kilobars. You can find only two conditions that offer these controls within the Earth. They're at the site of the attack by a meteorite or inside the earths lithospheric mantle and where it is below continental plates that are relatively stable. Diamonds are just produced deep within the world, at the very least 90 miles down, to a maximum of 120 miles deep. Of course, this depends on the geographical region since the rate of temperature change relative to depth is different in different areas. Under oceanic plates, for instance, the temperature will rise more quickly as you get further in the earth. Click Here is a stately library for further about why to mull over it. The only real place where you'll find just the right combination of temperature and pressure are the earliest, thickest and most secure elements of the earths continental dishes where lithosphere parts called cratons are found. The longer the diamond crystals live in the cratons the bigger the diamonds that result. We learned about for sea surface temperature by searching Google Books. The carbon that people find in diamonds originates from a variety of both organic and inorganic matter. Boffins have established this by studying rates of carbon isotopes, a way somewhat comparable to carbon dating. Some diamonds, named harzburgitic, have been formed from carbon that's inorganic and found in the deepest parts of the layer. Eclogitic diamonds, in comparison, include organic carbon that comes from organic detritus being sent by subduction from the surface of the earth. Diamonds that rise to the surface of the planet earth have reached least one billion years old and may be over three billion years. Often diamonds kind in other events that also have high-pressure and low temperature controls. Nanodiamonds and microdiamonds, the very smallest of the stone family, have been discovered inside impact craters, the results of meteors striking the-earth. The shock of the meteor moves actually produces the perfect temperature and pres-sure conditions that induce these diamonds. If you are concerned by law, you will certainly desire to research about about sea temperature . Source: http://en.wikipedia.org/wiki/Diamond.
