Arsenohauchecornite is a rare nickel-arsenic-antimony-tellurium sulfide mineral belonging to the hauchecornite group. It typically occurs as small metallic grains or tabular crystals within hydrothermal sulfide ore deposits, often requiring microscopic identification due to its similarity to other nickel sulfides.
Is this arsenohauchecornite?
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 arsenohauchecornite with a known reference. Arsenohauchecornite 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. Arsenohauchecornite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Arsenohauchecornite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: brass-yellow, bronze.
- 5Look at form & habitCrystal system: tetragonal. Typical habit: tabular crystals, massive.

Field-hunting tip
Look in hydrothermal sulfide veins country — that is the host setting where arsenohauchecornite typically forms. If you start seeing gersdorffite, millerite, chalcopyrite in float, you are in the right ground. Field specimens usually show a tabular crystals, massive habit, so train your eye for that shape before scanning the outcrop.
