Buseckite is a rare sulfide mineral first identified as microscopic inclusions within iron meteorites. It belongs to the wurtzite group and is primarily significant to scientific researchers studying extraterrestrial mineralogy and meteorite formation.
Is this buseckite?
3-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 buseckite with a known reference. Buseckite sits at Mohs 3.5-4, softer than the next harder reference, harder than the previous one.
- 2Match the color rangeCompare against the expected color range: black.
- 3Look at form & habitCrystal system: hexagonal. Typical habit: microscopic grains and inclusions.

Field-hunting tip
Where it forms: Iron meteorites. If you start seeing enstatite, plagioclase, troilite in float, you are in the right ground. Typical habit: microscopic grains and inclusions. Train your eye for that shape before scanning the outcrop.
