'''Xieite''' is an [iron](/source/iron) [chromium](/source/chromium) [oxide mineral](/source/oxide_mineral) with formula Fe<sup>2+</sup>Cr<sub>2</sub>O<sub>4</sub>. It is a member of the [spinel group](/source/spinel_group) and a high pressure [polymorph](/source/Polymorphism_(materials_science)) of [chromite](/source/chromite).<ref name=Mindat/>

It was discovered in samples taken from the [Suizhou meteorite](/source/Suizhou_meteorite) which fell in 1986 in the [Zengdu District](/source/Zengdu_District) of [China](/source/China).<ref name=Mindat/>
