Pyroxmangite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
MnSiO3
System:
Triclinic
Colour:
Pink, red, brown
Hardness:
5½ - 6
Name:
Named in 1913 by William E. Ford and W. M. Bradley from PYROXene and MANGanese, in allusion to its structure and content of Manganese.
Dimorph of:
Pyroxferroite-Pyroxmangite Series.

Easily confused with rhodonite; however, pyroxmangite is a high-temperature environment mineral and syntheses have shown that pyroxmangite of MnSiO3 composition is the high-pressure, low-temperature polymorph with respect to rhodonite of the same composition (Maresch & Mottana, 1976).
Both may occur together (Sterling Mine, NJ, USA).

Note: "Type material" from Iva, South Carolina, USA, has been redefined as pyroxferroite, as it has Fe > Mn.
