The Earth Reprocesses Ocean Floor Into Diamonds: Study Shows

Reportedly, the diamond is most possibly made of reprocessed seabed found deep in the Earth. The traces of salt stuck in many diamonds explain the stones are created from ancient seabeds that were buried deep beneath in the Earth’s crust, as per to new research conducted by geoscientists from Macquarie University, Sydney. Most of the diamonds found at the Earth’s exterior are created this way, while others are formed by crystallization of melting deep in the mantle. Professor Stephen Foley, Dr. Michael Forster, Dr. Olivier Alard, along with colleagues from Johannes Gutenberg University and Goethe University, while the study has demonstrated that seawater in sediment at the base of the ocean responds in the right mode to form the balance of salts seen in a diamond.

The study was published in Science Advances. Lead author Michael stated, “There was speculation that the salts stuck inside diamonds was from marine seawater, but could not be tested. Our research illustrated that they arise from marine sediment.” Apparently, diamonds are crystals of carbon that are formed under the Earth’s crust in extremely old parts of the mantle. They are carried to the surface during volcanic eruptions of a precise kind of magma known as kimberlite.

On a similar note, recently, a study showed the eclogitic diamonds are formed from oceanic crust. As per to new research from the University of Alberta, geologists state that eclogitic diamonds are formed in the Earth’s mantle originated from oceanic crust, instead of marine sediments as commonly believed. Reportedly, diamonds are discovered in two types of rocks from the Earth’s mantle that is eclogite and peridotite. Peridotite is the most ordinary kind of mantle rock, while eclogite is formed from igneous oceanic crust. Although, many researchers earlier believe that eclogitic diamonds are formed with carbon from marine sediment, which is a large carbon reservoir.
