What is Pyroxmangite?

Pyroxmangite has the general chemical formula of MnSiO3. It is the high-pressure, low-temperature dimorph of rhodonite. It was first described in 1913 and named for the mineral group, pyroxenes, and is known as the manganese member. It forms a series with pyroxferroite. Pyroxmangite occurs in metamorphosed ore deposits rich in manganese. Associated minerals include spessartine, tephroite, alleghanyite, hausmannite, pyrophanite, alabandite, rhodonite and rhodochrosite.
