Formula:
α-MnSiO3
or Mn3Si3O9
Colour:
violet-red
Crystal System:
Triclinic
Polymorph of:
Crystallographically fits to synthetic α-MnSiO3 and thus possibly represents the Mn analogue of pseudowollastonite.
Found as grains, in the upper part of Liassic crinoidal limestones of the Chochołowska valley, Western Tatra Mts., Poland. The manganese limestones contain calcite, "manganocalcite", rhodochrosite and Mn oxides.
