Ringwoodite, a compact modification of olivine (γ-olivine), was experimentally synthesized under static loads (within the interval 6-24 GPa, depending on the composition and the olivine-ringwoodite conversion temperature) ...
For five tektite glasses (moldavites, indochinites, and irgizite), oxygen fugacity (fO2) was measured within the temperature range of 800-1150°C using solid electrochemical cells, and water content was analyzed with FTIR ...
