Research paper thumbnail of High-pressure phase relations in the system CaAl4Si2O11–NaAl3Si3O11 with implication for Na-rich CAS phase in shocked Martian meteorites

Earth and Planetary Science Letters, 2010

High-pressure phase relations in the system NaAl3Si3O11–CaAl4Si2O11 were examined at 13–23GPa and... more High-pressure phase relations in the system NaAl3Si3O11–CaAl4Si2O11 were examined at 13–23GPa and 1600–1900°C, using a multianvil apparatus. A Ca-aluminosilicate with CaAl4Si2O11 composition, designated CAS phase, is stable above about 13GPa at 1600°C. In the system NaAl3Si3O11–CaAl4Si2O11, the CAS phase dissolving NaAl3Si3O11 component coexists with jadeite, corundum and stishovite below 22GPa, above which the CAS phase coexists with Na-rich calcium ferrite,
