Outline of Final Research Achievements |
This is the report of the investigation to clarify the P-T conditions for the armalcolite stability field through the high-pressure experiments at pressures 6~12 kbar and temperatures 900~1100℃ corresponding to the ultrahigh-temperature metamorphic conditions under controlling the oxygen fugacity (logPO2=-10~-11). In the TiO2-FeO-MgO system with bulk of 0.15<XMg<0.2, we found that the assemblage of armalcolite + ilmenite + rule is stable at 8 kbar and more than 900~950℃. This indicates Fe-rich armalcolite would be stable at pressures and temperatures conditions corresponding to the ultrahigh-temperature metamorphism under oxdising conditions (logPO2=-10~-11). We conclude the Fe-rich armalcolite would be a new index mineral for ultrahigh-temperature metamorphism.
