At a depth of 410 to 660 kilometers beneath the Earth’s surface contains the same amount of water as in the oceans.
An international team of geologists estimated contained in a giant underground ocean of the Earth’s water supply. A study published in the journal Science Advances.
At a depth of 410 to 660 kilometers beneath the Earth’s surface, in the layer that separates the upper mantle from the lower, contains, according to scientists, the same amount of water as in the oceans.
Experts ‘ calculations, based on simulation conditions, which are minerals, in particular ringwoodite in the mantle of the planet. It turned out that the inclusion of water in this mineral (1-2 percent by weight) gives it the observed viscosity.
In March, the Geochemistry of Russia, France and Germany found at a depth of 410-660 kilometers beneath the Earth’s surface the ocean the Archean period (2.7 billion years), the volume of which (but not weight), they estimated that in times exceeds the size of the oceans. A huge body of water located under the earth’s crust and formed in ancient times under the conditions of high pressures and temperatures (1530 ° C). The water is enclosed in the crystalline structure of minerals.
