Abstract
The FeSiO3 (ferrosilite) end member of the pyroxene series is not known as a pure mineral in nature and cannot be synthesized at atmospheric pressure. It is readily synthesized, however, at pressures from 18 to 45 kb and temperatures from 1150°to 1400°C. Its refractive indices approach those predicted for ferrosilite and it melts incongruently to an Fe, SiO4-rich liquid plus quartz.Keywords
