  • Hellandite-(Ce): Mineral information, data and localities.

    www.mindat.org/min-27087.html In the IMA approved report on hellandites (Oberti et al., 2002), 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 formula of hellandite-(Ce).
  • Hellandite-(Y): Mineral information, data and localities.
