Kimberlites and Diamond Formation

Origin and Formation of Diamonds through Kimberlite Pipes Diamonds form from kimberlite pipes. They argon brought to the materialization as inclusions in kimberlite rocks. They form at great judiciousness in the Earth and the explosive diatreme volcanism is strong enough to recurrence aim them to the grow. T present be many kimberlite mines that atomic number 18 presently in operation. They are spread over the world. approximately 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 heavy within the Earth, about 100 miles under the surface in the upper mantle. They are composed exclusively of carbon, demur for some trace impurities at times. In enact for a diamond to be created, carbon must be dictated under a least 30 kilobars of instancy at a temperature of at least 400 degrees Celsius (Arima 1993). Most diamonds that we hang today were formed mi llions of years ago. Powerful 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 bang 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 flack 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 determine little about kimberlite eruptions, as compared to basaltic eruptions, for example. Also, because most kimberlite blowholees are over 30 million years old, they are steadfastly eroded, and the surface parts that we would recognize as a release have been removed. Diamonds are the hardest naturally occurring materials on earth. Thanks to its covalent bonding, d! iamonds have a relative hardness of 10 on the Mohs...If you want to get a full essay, order it on our website: OrderEssay.net
