Species: | Barroisite |
Formula: | ◻{CaNa}{Mg3Al2}(AlSi7O22)(OH)2 |
Comments: | According to Mattinson et al (2004) are barroisite found as rims on talc and as large blue-gray barroisite poikiloblasts. An analysis of the latter type corresponds to winchite in the 2012 amphibole nomenclature and the occurrence is questionable. |
