Lepidocrocite (γ-FeO(OH)) also called esmeraldite or hydrohematite is an iron oxide-hydroxide mineral. Lepidocrocite has an orthorhombic crystal structure a hardness of 5 specific gravity of 4 a submetallic luster and a yellow-brown streak. It is red to reddish brown and forms when iron-containing substances rust underwater. Lepidocrocite is commonly found in the weathering of primary iron minerals and in iron ore deposits.
