“White meionite crystals (confirmed by SEM-EDS, see child photo) in a cleft in calc-silicate rock, with dark green actinolite underneath and some epidote at lower right. Former Ronald Januzzi collection.”

“SEM-EDS analyses performed by Tom Mortimer and Peter Cristofono, courtesy of the Boston College microscopy lab. The abundance of Ca over Na shows it to be the Ca member of the series, meionite, with some impurity by marialite Na and Cl. The trace of potassium is not unusual.”
