Chemical Properties

Chemical Formula: (Ca,REE)4Y2Al◻2(B4Si4O22) (OH)2 In the IMA approved report on hellandites [Am. Mineral.,87 (2002), 745–752], the occupancy at the T sites was given as (Be,Li)2–x however the value of x was not specified. Actually it is always x > 1, therefore the T site is vacant in the ideal formulae of hellandite-(Y).
