Galuskinite is a rare calcium silicate carbonate mineral found in high-temperature skarn environments. It is typically identified through its association with other lime-silicate minerals and its distinct X-ray diffraction pattern.
Is this galuskinite?
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 galuskinite with a known reference. Galuskinite 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. Galuskinite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Galuskinite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: colorless, white, pale yellow.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: tabular crystals, massive, granular.

Field-hunting tip
Look in skarn deposits country — that is the host setting where galuskinite typically forms. If you start seeing wollastonite, calcite, rankinite in float, you are in the right ground. Field specimens usually show a tabular crystals, massive, granular habit, so train your eye for that shape before scanning the outcrop.
