Chemical Properties

Chemical Formula: {Na}{Na2}{Mn2+4Fe3+}Si8O22(OH)2 The Eckermannite minerals are sodium amphiboles defined with A(Na+K+2Ca)> 0.5 apfu and 0.5 apfu < C(Al+Fe3++2Ti) < 1.5 apfu with Al>Fe3+ in the C3+ position. Normally if Fe3+ > Al, these minerals are named with an arvfedsonite root-name. For some reason, it has been decided to introduce the name ferri-eckermannite for this mineral. Mangano-ferri-eckermannite is defined with A position: Na dominant C2+ position: Mn dominant C3+ position: Fe dominant W position: (OH) dominant
Elements: Fe, H, Mn, Na, O, Si
