Hezuolinite is a rare, barium-rich feldspar mineral that is part of the alkali feldspar series. It was first identified in syenite porphyry rocks in the Hezuo region of China and is primarily sought after by mineral collectors for its unique compositional characteristics.
Is this hezuolinite?
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 hezuolinite with a known reference. Hezuolinite sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Hezuolinite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Hezuolinite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: white, pale yellow.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: granular to massive.

Field-hunting tip
Look in syenite porphyry country — that is the host setting where hezuolinite typically forms. If you start seeing quartz, biotite, plagioclase in float, you are in the right ground. Field specimens usually show a granular to massive habit, so train your eye for that shape before scanning the outcrop.
