Formula:
â»{CaNa}{Mg3Al2}(AlSi7O22)(OH)2
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).

C2+ position: Mg dominant

Name:
Named in 1922 by Murgoci in honor of Charles Eugene Barrois (April 21, 1851, Lilles, France - November 5, 1939, St Genevieve-en-Caux, France), French geologist and palaeontologist.
Type Locality:
Barroisite is defined as a barroisite-group member 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 â(NaCa)(Mg3AlFe3+)(AlSi7O22)(OH)2 to â(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.
