The barroisite group minerals are sodium-calcium amphiboles defined with A(Na+K+2Ca)< 0.5 apfu and 1.5 apfu < C(Al+Fe3++2Ti).

Barroisite is defined with

C2+ position: Mg dominant
C3+ position: Al dominant
W position: (OH) dominant
System:MonoclinicColour:Bluish-green to green.
Lustre:VitreousHardness:5 - 6
Member of:Barroisite Root Name Group > Sodium-Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup
Name:Named in 1922 by Murgoci after the French geologist Charles BARROIS (1851-1939 )


Barroisite is defined as a barroisite-group memeber with Mg>Fe2+ and Al>Fe3+ in the C position. Barroisite has been redefined in the 2012 Amphibole nomenclature in that:


1) The formula is changed from ☐(NaCa)(Mg3AlFe3+)(AlSi7O22)(OH)2 to ☐(NaCa)(Mg3Al2)(AlSi7O22)(OH)2. Consequently all pre-2012 literature references to barroisite should be checked to verify that Al>Fe3+ in the C position. If Fe3+>Al in the C position the material will be ferri-barroisite.

2) The barroisite group is in the 2012 nomenclature defined with C(Al+Fe3++2Ti)>1,5 apfu, whereas the pre-2012 definition was defined with 6,5 < Si < 7,5 apfu. This redefinition does not change the formula, but some amphiboles qualifying as barroisite pre-2012 will now be winchite or ferri-winchite. Since the content of the C3+ position was not part of the pre-2012 definition, it was often omitted in the presentation of data.
