Diamonds are to be buried for 400 miles below the surface, it would be able to explain the mysterious earthquakes

SAN FRANCISCO — Deep in the Earth, earthquakes, roaring in the mantle’s transition zone, is the area that divides the upper mantle from the lower. The fluid in the mantle is thought to have an important role to play in the management of deep earthquakes, but so far, it’s not a smoking gun, to prove that the liquid is present at this point.

Now, scientists believe they have found evidence of a liquid in an unlikely place: “in superdeep diamonds.

Even though the majority of diamonds will crystallize at a depth of 87 to 124 miles (140 to 200 km), superdeep diamonds have been found so far with a total of 373 to 497 miles (600 to 800 km below the surface. The inside of this jewelry is forged in the depth of its minor flaws, or inclusions, made by the kind of liquid. This defect indicates that it is probable that the liquid flow in the mantle layer, where the diamonds are being formed.

It is a liquid, which is in the best interests of scientists to study the deep Earth, geochemist Steven Shirey, a senior research scientist at the Carnegie Institution for Science in Stanford, California, told Science at the annual meeting of the American Geophysical Union (AGU). This is because of the location and the movement of these fluids may be the key to the understanding of deep earthquakes, Shirey said.

In a new study, presented at the AGU meeting will be on Tuesday, Dec. 10), Shirey and his colleagues have modeled the motion of the fluid at the depth of information on the locations of these diamonds formed in the mantle.

The advantage of these models, the scientists hope to connect the dots on the bottom of the flowing movement, deep in the mantle, diamond formation, “and to the physical rupture of the properties of the rocks in the region of the mantle transition zone, Shirey said. As a next step, researchers need to relate to the flow of these fluids to deep-focus earthquakes,” he said.

The deep earthquakes are energized, high frequency, and is a very interesting manifestation of plate tectonics — is a bit more bitter than we are able to see plate tectonics,” Shirey said.

Just what happens at the boundary of plate tectonics, it turns out to be a very interesting planet in question,” he said.
