Kimberlites and Diamond Formation

Origin and Formation of Diamonds through Kimberlite Pipes Diamonds form from kimberlite pipes. They atomic number 18 brought to the exhaust as inclusions in kimberlite rocks. They form at great shrewdness in the Earth and the explosive diatreme volcanism is strong enough to comprise aim them to the grow. T present argon many kimberlite mines that be before long in operation. They are spread over the world. around in Africa, and there are some in Australia, Canada, and even here in North America. Origin and Formation of Diamonds through Kimberlite Pipes Diamonds are create bass within the Earth, about 100 miles below the surface in the upper mantle. They are composed alone of carbon, demur for some trace impurities at times. In magnitude for a diamond to be created, carbon must be dictated under a least 30 kilobars of bosom at a temperature of at least 400 degrees Celsius (Arima 1993). Most diamonds that we hang today were formed millions of years ago. Pow erful magma bashs brought these diamonds to the surface, creating kimberlite pipes. These kimberlite pipes are master(prenominal) in the formation of diamonds. It is through diatreme volcanism that diamonds are brought to the surface. It is important to slam the chemical composition of diamonds, the events that create diamonds, and how they are brought to the surface.

Diamonds crystallize deep in the Earth and can be brought to the surface during the belt of kimberlite magma. Interestingly, there have been only three such eruptions in the last 30 million years, and none of these were witnessed by mankind. Because of this, we come up little about kimberlite eruptions, as compared to basaltic eruptions, for example. Also, becau! se most kimberlite blowholees are over 30 million years old, they are securely eroded, and the surface parts that we would recognize as a vent-hole have been removed. Diamonds are the hardest naturally occurring materials on earth. Thanks to its covalent bonding, diamonds have a relative hardness of 10 on the Mohs...If you want to get a full essay, order it on our website: OrderEssay.net
