Scientists were shocked when a never-before-seen mineral was found inside a diamond that was extracted from deep beneath the Earth's surface.The mineral was named davemaoite, after the prominent geophysicist Ho-Kwang (Dave) Mao.
It is the first example of a high-pressure calcium silicate perovskite (CaSiO3) found on Earth.While another form of CaSiO3, known as wollastonite, is commonly found across the globe, this version has a crystalline structure that can only form under high pressure and high temperatures in Earth's mantle - the mainly solid layer of Earth trapped between the outer core and the crust.While davemaoite has never been seen before, it is expected to be found in abundance in the Earth's mantle and is a geochemically.
