Mt. Erebus anorthoclase is the most calcic one-phase anorthoclase which was twinned according to the albite-and pericline-laws in the course of monoclinic-triclinic inversion, whose temperature was measured to be 750℃. The occurrence of the one-phase anorthoclase was closely related with the eruption mechanism of Mt. Erebus.}, pages = {66--72}, title = {MICROSTRUCTURE AND PHASE TRANSITION OF CALCIC ANORTHOCLASE FROM MOUNT EREBUS, ANTARCTICA}, volume = {1}, year = {1987} }
