Kaitianite is an extremely rare titanium oxide mineral discovered within the Kaitian impact crater. It occurs as microscopic, opaque metallic grains associated with high-pressure impactites and is primarily of interest for advanced mineralogical study.
Is this kaitianite?
2-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 kaitianite with a known reference. Kaitianite sits at Mohs 6, softer than the next harder reference, harder than the previous one.
- 2Look at form & habitCrystal system: monoclinic. Typical habit: anhedral to subhedral grains.

Field-hunting tip
Where it forms: In a CV3 carbonaceous chondrite meteorite. If you start seeing tistarite, rutile, ti-xifengite in float, you are in the right ground. Typical habit: anhedral to subhedral grains. Train your eye for that shape before scanning the outcrop.
