ⓘ Katophorite

Formula: {Na}{CaNa}{Mg₄Al}[(AlSi₇)O₂₂](OH)₂

Description: Byramjee R.and Meindre M.(1956)publish the following normalized amphibole composition: (Na_0.394K_0.243)_0.637(Na_1.242Ca_0.758)_2.00(Mg_4.139Mn_0.311Fe_0.068Al_0.471Ti_0.010)_5.00(Si_7.894Al_0.106)O₂₂((OH)₂. Their data does not give a Fe³⁺/(Fe³⁺ + Fe²⁺) ratio, but charge balance calculations give sufficient Fe³⁺ for the amphibole to fall within the katophorite range as defined by Hawthorne et al. (2012)
