REVISED CHEMICAL FORMULAE

Hellandite-(Ce) and hellandite-(Y)

In the IMA List of Minerals the chemical formulae of hellandite-(Ce) and hellandite-(Y) were inconsistent with those given in the IMA-approved report on hellandites [Am. Mineral., 87 (2002), 745–752].

In both formulae 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-(Ce) and hellandite-(Y). Now both formulae have been modified accordingly: (Ca,REE)4Ce2Al□2(B4Si4O22)(OH)2 and (Ca,REE)4Y2Al□2(B4Si4O22)(OH)2, respectively.
