Water exists deeper in Earth than thought: study Water exists far deeper in the Earth - about 400 to 600 kilometres into the mantle - than previously believed, researchers including one of Indian origin have found. A mineral far below the surface of the Earth may hold the key to how much water is stored in our planet, researchers said. Mainak Mookherjee, Assistant Professor at Florida State University in the US and Andreas Hermann from the University of Edinburgh in the UK estimate that in the deep Earth - roughly 400 to 600 kilometres into the mantle - water is stored and transported through a high-pressure polymorph of the mineral brucite. Previously, scientists thought brucite was not thermodynamically stable that deep in the Earth. http://www.deccanherald.com/content/582447/water-exists-deeper-earth-thought.html
