**Pyroxmangite** has the general chemical formula of MnSiO3.[5] It is the high-pressure, low-temperature [dimorph](/source/Polymorphism_(materials_science)) of [rhodonite](/source/Rhodonite).[2]

It was first described in 1913 and named for the mineral group, [pyroxenes](/source/Pyroxene), and is known as the [manganese](/source/Manganese) member.[6] It forms a series with [pyroxferroite](/source/Pyroxferroite).

Pyroxmangite occurs in [metamorphosed](/source/Metamorphism) ore deposits rich in manganese. Associated minerals include [spessartine](/source/Spessartine), [tephroite](/source/Tephroite), [alleghanyite](/source/Alleghanyite), [hausmannite](/source/Hausmannite), [pyrophanite](/source/Pyrophanite), [alabandite](/source/Alabandite), rhodonite and [rhodochrosite](/source/Rhodochrosite).[4]
