A diamond containing a never-before-seen form of calcium silicate (CaSi03) and traces of titanium sheds light on the composition and dynamics of the Earth\u2019s inner workings. Although scientists have theorized that this form of CaSi03 is widespread within the planet, the mineral remains stable at only extremely high pressures\u2014such as those found at depths below 600 kilometres\u2014or when protected within a diamond that originates that far down in the Earth. The mineral\u2019s structure, presence of titanium, and diamond\u2019s composition indicate the material that makes up the oceans\u2019 floors recycles to the Earth\u2019s lower mantle.<\/p>\n
