Mineral revolution (IMAGE)
Caption
Working with magnesium germanate, Mg2GeO4, analogous to one of the mantle’s most abundant silicate minerals, the team was able to glean information about the potential mineralogy of super-Earths and other large, rocky exoplanets. Under about 2 million times normal atmospheric pressure a new phase emerged with a distinct crystalline structure that involves one germanium bonded with eight oxygens. The new eight-coordinated, intrinsically discorded mineral is expected to strongly affect the internal temperature and dynamics of these planets. Illustration is courtesy of Rajkrishna Dutta.
