Hercynite is a mineral, specifically an iron aluminum oxide (FeAl₂O₄), belonging to the spinel group.

Where is hercynite commonly found?

It is found in high-temperature metamorphic rocks like some schists and hornfels, and in certain silica-poor igneous rocks.

Does hercynite have any economic uses?

It has minor specialised uses, such as in some refractory ceramics, but is primarily of scientific interest for understanding geological processes.

How do you pronounce hercynite?

In British English: /ˈhɜːsɪnaɪt/ (HER-si-nyte). In American English: /ˈhɝːsɪnaɪt/ (HUR-si-nyte).
