Pyroxmangite has the general chemical formula of MnSiO3 [5] dimorph of rhodonite .[2]
It was first described in 1913 and named for the mineral group, pyroxenes , and is known as the manganese member.[6] pyroxferroite .
Pyroxmangite occurs in metamorphosed ore deposits rich in manganese. Associated minerals include spessartine , tephroite , alleghanyite , hausmannite , pyrophanite , alabandite , rhodonite and rhodochrosite .[4]
