Crystalline-amorphous materials. Important in the Earth and in industry

David L. Kohlstedt

Research output: Contribution to journalArticlepeer-review


In many regions of the earth, silicate rock reaches temperature and pressure conditions at which it partially melts. This rock transports heat and mass more readily than ordinary silicates do, and it creates zones of high seismic attenuation, reduced strength, and increased electrical conductivity. Geological silicates and glass-ceramic materials have similar structures: they are composed of one or more crystalline phases plus an amorphous or melt phase. They constitute an important class of materials, characterized as crystalline-amorphous.
