About FluorcalcioroméiteHide
This section is currently hidden. Click the show button to view.
Formula:
(Ca,Na,◻)2Sb5+2(O,OH)6F
Lustre:
Vitreous, Resinous
Specific Gravity:
5.113 (Calculated)
Name:
The name was created during a 2010 reorganization of the pyrochlore supergroup, but it required a complete description in order to be approved as valid species. That description was published in 2013. The name indicates the chemical relationship to other roméite group species.
