Confirmed: The earth breaks the ocean into salt diamonds

Science

It has been said that diamonds are forever – perhaps because “diamonds are too often mutated by billions of stones of heat and temperature in the deep mantle of the earth” pushing the same ring.

However, it took a very long time for crystals to crystallize in sparkling diamonds – so long that scientists weren’t sure how to do it. A general theory is that many diamonds form when the seabed plate (part of the oceanic plate) is in soil called a tectonic subduction zone under the continental plate. During the process of the oceanic plate and all minerals on the seabed down hundreds of miles into the mantle, which at high temperatures and pressures slowly crystallize tens of thousands of times greater than those on the surface. Finally, these crystals are mixed with volcanic magma called kimberlite and explode like diamonds on the surface of the planet.

Support for this theory can be found in oceanic minerals that give their signatures on blue stones – like “Hope” embarrassing (and possibly cursed) diamonds. However, diamonds are among the deepest, rarest, and most expensive in the world, which is why they are difficult to learn. Studies published today (May 29) in Science Advances provide new evidence for the origin of diamond oceans. For this study, the researchers studied saline sediment deposits in far more common rocks known as fibrous diamonds.

Unlike most diamonds used in wedding attributes, fibrous diamonds run away with a small amount of salt, potassium, and other substances. They are less valuable for jewelry, but may be more valuable to scientists who want to find their underground origin.

“There is a theory that salt from seawater caught in diamonds is, but cannot be tested,” said Michael Forster, a professor at Macquarie University in Australia and lead author of the new study.

So the original Forster diamond and its original colleagues, without a trace, tried to create a svrahpoglashtashti reaction in his laboratory which occurred when minerals on the seafloor fell into the mantle. The team filled the seaweed into a mineral container called peridotitis. This is a volcanic rock that is widespread in the depths where it should form diamonds. then they mix with a combination of heat and pressure conditions that mimic those found in the mantle.

Researchers have found that when mixtures are pressed from 4 to 6 gigapascals (40,000 to 60,000 times the average sea surface air pressure) and temperatures between 1,500 and 2,000 degrees Fahrenheit (800 to 1,100 degrees Celsius) Salt is formed with almost identical properties as in fibrous diamonds. In other words, when the old seabed slides into the inner mantle, the impact force creates the perfect conditions for diamond formation. In this way, gemstones can also be made, which consists of pure carbon and does not contain sediment deposits.

“We know there must be some kind of salt liquid when the diamond grows, and now we have confirmed that seaweed meets the bill,” said Fehster. He added that the same experiments that produce and minerals that are important for the formation of kimberlite on diamonds usually move to the surface of the earth during volcanic eruptions.

So diamonds really can be part of the ancient ocean story that you carry on your finger. And if this gem is too expensive for your taste, don’t worry – you can still bring a piece of the past on this planet by pulling a gold or platinum ring. According to a recent study in the journal Nature, this trace of shiny minerals in a common type of jewelry is likely due to the battle of epic neutron stars, which literally invaded the solar system 4,600,000,000,000 years ago.
