About Pyroxmangite
Formula:
Mn2+SiO3
Colour:
Pink, red, brown
Lustre:
Vitreous, Pearly
Hardness:
5½ - 6
Specific Gravity:
3.61 - 3.80
Crystal System:
Triclinic
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.
Polymorph of:
Pyroxferroite-Pyroxmangite Series.
Easily confused with rhodonite or vittinkiite; 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 pyroxmangite and rhodonite may occur together (Sterling Mine, NJ, USA).
Compare mendigite and UM1975-18-SiO:Mn - the unnamed α-MnSiO3 phase from limestones of Polish Tatra Mts.
Note: "Type material" from Iva, South Carolina, USA, has been redefined as pyroxferroite, as it has Fe > Mn.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
