A sample of lepidocrocite

Lepidocrocite (γ-FeO(OH)), also called esmeraldite or hydrohematite, is an iron oxide-hydroxide mineral. A number of species are dubbed iron(III oxide-hydroxide. These chemicals are Oxide - Hydroxides of Iron, and may occur in Anhydrous (( or A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Lepidocrocite has an orthorhombic crystal structure, a hardness of 5, specific gravity of 4, a submetallic luster and a yellow-brown streak. In Crystallography, the orthorhombic Crystal system is one of the seven Lattice Point groups Orthorhombic lattices result from stretching In Mineralogy and Crystallography, a crystal structure is a unique arrangement of Atoms in a Crystal. The Mohs scale of mineral hardness characterizes the scratch resistance of various Minerals through the ability of a harder material to scratch a softer material Specific gravity is defined as the ratio of the Density of a given solid or liquid substance to the density of water at a specific temperature and pressure typically Lustre (or luster) is a description of the way light interacts with the surface of a Crystal, rock, or Mineral. It is red to reddish brown and forms when iron-containing substances rust underwater. Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 Rust is a general term for a series of Iron oxides, usually red oxides formed by the reaction of Iron with Oxygen in the presence of water or air Lepidocrocite is commonly found in the weathering of primary iron minerals and in iron ore deposits. Weathering is the decomposition of earth rocks, Soils and their Minerals through direct contact with the planet's Atmosphere. Iron ores are rocks and Minerals from which Metallic Iron can be economically extracted It can be seen as rust scale inside old steel water pipes and water tanks. Steel is an Alloy consisting mostly of Iron, with a Carbon content between 0 For the various smoking devices see Hookah or Bong. For other uses see Pipe.

The structure of lepidocrocite is similar to the boehmite structure found in bauxite and consists of layered iron(III) oxide octahedra bonded by hydrogen bonding via hydroxide layers. Boehmite or Böhmite is an Aluminium oxide hydroxide (γ-AlO(OH mineral a component of the aluminium ore Bauxite. Bauxite is the most important Aluminium Ore. It consists largely of the minerals Gibbsite Al(OH3 Boehmite γ-AlO(OH and A hydrogen bond results from a Dipole-dipole force between an Electronegative atom and a Hydrogen atom bonded to Nitrogen, Oxygen In Chemistry, hydroxide is the most common name for the diatomic Anion OH− consisting of Oxygen and Hydrogen This relatively weakly bonded layering accounts for the scaley habit of the mineral.

It was first described in 1813 from the Zlaté Hory polymetallic ore deposit in Moravia, Czech Republic. Primarily used in Chemistry or Mining, polymetal or polymetallic refers to a substance comprised of a combination of different Metals. An ore is a volume of rock containing components or Minerals in a mode of occurrence that renders it valuable for mining Moravia (Morava; Morawy Moravie Moravia is a historical region in central Europe in the east of the Czech Republic, one of the former Czech lands. The Czech Republic ( ˈt͡ʃɛskaː ˈrɛpuˌblɪka short form in Česko ˈt͡ʃɛskɔ also called Czechia, The name is from the Greek lipis for scale and krokis for fibre.
