Metastable silica high pressure polymorphs as structural proxies of deep Earth silicate melts

As silica melts are believed to be important components of the Earth’s mantle, their structure should determine many of its properties. Here, the authors identify two crystalline modifications of SiO2, whose local structures closely resemble those of known melts, providing a structural model for the...
