A variety of Pyrochlore Supergroup
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ca,Sb3+)2(Ti,Nb,Ta)2(O,OH)7
Formula as given by in Hey's 3rd ed.
Colour:
Dark brown
Lustre:
Greasy
Hardness:
5
Crystal System:
Isometric
Name:
The name reflects its antimony (Greek = STIBI) content and relationship to Pyrochlore.
Černý et al. (1979) defined stibiobetafite as the Sb3+ analogue of betafite; however, the type sample has Nb + Ta > Ti apfu, and Ca is the dominant species of the dominant-valence group at the A site. The type sample is now to be classified as oxycalciopyrochlore.
It is not possible to calculate the formula of stibiobetafite studied by Tindle & Breaks (1998) owing to errors in the table of analytical data.
