About Pyrosmalite-(Mn)Hide

Formula:
Mn2+8Si6O15(OH,Cl)10
Hardness:
Crystal System:
Trigonal
Name:
Originally named manganpyrosmalite by By Clifford Frondel and Lawson H. Bauer for its manganese-dominant composition relative to the original pyrosmalite. Both pyrosmalites were later given suffixes, -(Mn) or -(Fe) by the IMA to indicated cation dominance in the chemical formula
Isostructural with:
Pyrosmalite-(Fe)-Pyrosmalite-(Mn) Series.
Chemically very similar to friedelite (monoclinic-pseudorhombohedral) and mcgillite.
