Secrets to Earth's interior found trapped in diamonds

Ученые обнаружили внутри алмазов лед с других планет

According to a report from the Los Angeles Times, ice-VII differs from regular ice, or ice-I, as oxygen atoms are arranged in a cubic shape, instead of hexagonal shape.

Before the release of the new findings, which were published Thursday in the journal Science, researchers had yet to discover ice-VII occurring naturally on our planet.

What we know as ice is just one of many chemical structures that frozen water can take.

Scientists have found another kind of water known as Ice VII from diamonds deep in the Earth's outside. Other known sites of its existence are Jupiter's moon Europa, and Saturn's moons Titan and Enceladus. Recently, researchers were looking for molecular forms of carbon dioxide in the Earth's mantle when they stumbled across diamonds spewed from volcanoes and found traces of new water ice inside them. Rarely, substances such as water get trapped inside.

China urges US, DPRK to conduct dialogue as soon as possible
US soy beans, aircraft and cars are widely seen as vulnerable to possible retaliation from Beijing . Japan and South Korea expressed alarm Friday at the potential economic damage from U.S.

They found out that diamonds which came from around 410 and 660 kilometers depth had a number of ice-VII in them.

"The presence of water in the diamond has always been known, but the discovery of the shape of the ice formed under ultrahigh pressure, we really struck", says Professor George Rossman. "But if a diamond comes up fast enough, it doesn't change". Thanks to the find, ice-VII has now officially been recognized as a mineral by the International Mineralogical Association. In other words, the new form of ice serves as an indicator for water-rich regions and can provide valuable clues to the inner workings of our planet because it is not possible to extract samples from very far below.

A group of scientists led by Oliver Tschauner, a professor of geoscience from the University of Nevada, have discovered a form of super-dense ice known as ice-VII on Earth for the first time.
