Existence of water in Earth’s lower mantle: A diamond study

by Jodie Jackson, RX Science

In a recent study, the scientists have discovered water within the lower mantle of Earth. According to the new discovery, unexpected amounts of water is present about 640 km deep inside the Earth and possibly beyond. They got their research published in the journal Science. This study leads to new questions like whether we are aware of the presence of water down below our planet. Also what else we could find there.

A team of scientists recently explored some sampling of diamonds which they obtained from around the world. They discovered microscopic pockets of a trapped form of crystallized water molecules in the sampling.

They followed various techniques to study the diamond samples from different locations in China and Africa. In these techniques, they used infrared light underneath a high-intensity X-ray machine known as the synchrotron. They observed tiny traces of crystallized water trapped in the spaces of the samples known as inclusions of just a few microns.
