..., magnesiostaurolite, zincostaurolite, and enstatite + sapphirine. Many of these phases were newly discovered solid-solution members of known minerals, but completely new rock-forming minerals like bearthite and ellenbergerite were studied as well. Nevertheless, Christian Chopin was also intrigued by the structure...
