About Taramite Root Name GroupHide

Formula:
A(CaNa)(C2+3C3+2)(Al2Si6O22)W2
The taramite minerals are sodium-calcium amphiboles defined with A(Na+K+2Ca)> 0.5 apfu and 1.5 apfu < C(Al+Fe3++2Ti).

The individual taramite minerals are defined by the dominant elements in the A, C and W positions. The most common dominant elements in the various positions are:
A position: Na or K dominant
C2+ position: Mg or Fe2+ dominant
C3+ position: Al or Fe3+ dominant
W position: (OH) or F dominant
Lustre:
Vitreous
Name:
Named for the group type locality, Walitarama, Mariupol, Ukraine.

The taramite group was redefined in the 2012 amphibole nomenclature. The following changes was made:

1) The taramite root name was redefined from the Fe2+ dominant species. The consequence of this is that all taramite group minerals without prefix pre-2012 will now have a ferro-prefix, and all taramite group minerals with a magnsio-prefix pre-2012 will now be without prefix.

2) Pre 2012, taramite and magnesiotaramite was defined with with Al ≈ Fe. Magnesiotaramite is now discredited, being either taramite or ferri-taramite, depending whether Al or Fe3+ is dominant, and taramite is redefined to be the Mg and Al dominant species in the group

3) The taramite group is in the 2012 nomenclature defined with C(Al+Fe3++2Ti)>1,5 apfu, whereas the pre-2012 definition was used the T position, i.e 5,5 < Si < 6,5 apfu. This redefinition does not change the formula, but some amphiboles qualifying as taramite group members pre-2012 may now belong to the katophorite group.
