Fluorcarmoite-(BaNa) is a rare amphibole group mineral characterized by its distinct barium and sodium composition within its crystal lattice. It is typically found in alkaline igneous complexes, often appearing as dark prismatic crystals within pegmatites or nepheline syenites.
Is this fluorcarmoite-(bana)?
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 fluorcarmoite-(bana) with a known reference. Fluorcarmoite-(BaNa) sits at Mohs 5-6, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Fluorcarmoite-(BaNa) leaves a yellow-orange streak.
- 3Read the lusterHold the specimen under a strong light. Fluorcarmoite-(BaNa) typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow-orange.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip
Look in alkaline igneous rocks country, the host setting where fluorcarmoite-(bana) typically forms. If you start seeing aegirine, nepheline, microcline in float, you are in the right ground. Field specimens usually show a prismatic crystals habit, so train your eye for that shape before scanning the outcrop.
