Pseudobrookite is an iron titanium oxide mineral with formula: Fe2TiO5[2] or (Fe3+,Fe2+)2(Ti,Fe2+)O5.

[3] Pseudobrookite was first described in 1878 for an occurrence in Uroi Hill (Arany Hill), Simeria, Hunedoara County, Romania.

The name is from Greek ψευδής, for false, and brookite because of its misleading similar appearance to brookite.

[2] Pseudobrookite forms as pneumatolytic deposition and alteration within titanium-rich volcanic rocks such as andesite, rhyolite or basalt.

[4] It occurs associated with hematite, magnetite, bixbyite, ilmenite, enstatite-ferrosilite, tridymite, quartz, sanidine, topaz, spessartine, beryl, mica, cassiterite and apatite.
