Manganotychite is a rare manganese-dominant member of the tychite group, primarily known from unique alkaline rock environments. Collectors typically look for small, sharp, pale pink to white pseudo-octahedral crystals that often appear in cavities within intrusive rocks.
Is this manganotychite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch manganotychite with a known reference. Manganotychite sits at Mohs 4, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: white.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous to dull.
- 4Match the color rangeCompare against the expected color range: brown, white, pink.
- 5Look at form & habitCrystal system: cubic. Typical habit: equant pseudo-octahedral crystals.

Field-hunting tip
Where it forms: An uncommon mineral formed in pegmatite veins in a differentiated alkalic massif (Mt. Alluaiv, Kola Peninsula, Russia). If you start seeing shortite, pirssonite, sidorenkite in float, you are in the right ground. Typical habit: equant pseudo-octahedral crystals. Train your eye for that shape before scanning the outcrop.
