limonite

li·mo·nite

L0176000 (lī′mə-nīt′)n. Any of a group of widely occurring yellowish-brown to black iron oxide minerals, essentially FeO(OH)·nH₂O, used as a minor ore of iron.

[Originally, bog iron ore, from German Limonit (coined on the model of German Wiesenerz : Wiesen, meadow + Erz, ore) : Greek leimōn, meadow, moist grassy place (of unknown origin) + German -it, -ite (from Latin -ītēs; see -ite¹).]

limonite

(ˈlaɪməˌnaɪt) n (Minerals) a common brown, black, or yellow amorphous secondary mineral that consists of hydrated ferric oxides and is a source of iron. Formula: FeO(OH).nH2O[C19: probably from Greek leimōn, translation of earlier German name, Wiesenerz meadow ore] limonitic adj

li•mo•nite

(ˈlaɪ məˌnaɪt)

n. a brown-to-yellow mineral mixture, mostly noncrystalline iron hydroxide with hematite and goethite: an ore of iron. [1815–25; < Greek leimṓn meadow + -ite¹ (so called from its typical location, in bogs or wet meadows)] li`mo•nit′ic (-ˈnɪt ɪk) adj.

limonite

(līm`ənīt) or

brown hematite

(hĕm`ətīt, hē`–), yellowish to dark brown mineral, a hydrated oxide of iron, FeO(OH)·nH₂O, occurring commonly in deposits of secondary origin, i.e., those formed by the alteration of minerals containing iron. Both iron rust and bog iron ore are limonite. It serves as a pigment (see ocherocher
, mixture of varying proportions of iron oxide and clay, used as a pigment. It occurs naturally as yellow ocher (yellow or yellow-brown in color), the iron oxide being limonite, or as red ocher, the iron oxide being hematite.

Limonite

collective name for natural cryptocrystalline, partially amorphous mineral aggregates comprising various minerals—hydrous trivalent iron oxides (for example, goethite, hydrogoethite, hydrohematite, lepidocrocite). Limonite is formed under exogenous conditions upon decomposition of pyrite and other iron-bearing sulfides, siderite, and iron silicates. It occurs in gossan, laterite, bog ore, and other similar-type formations. Limonite forms large industrial deposits of high-grade iron ore.

limonite

[′lī·mə‚nīt] (mineralogy) A group of brown or yellowish-brown, amorphous, naturally occurring ferric oxides of variable composition; commonly formed secondary material by oxidation of iron-bearing minerals; a minor ore of iron. Also known as brown hematite; brown iron ore.

limonite

A naturally occurring mineral which is used in high-density concrete because of its high density and water content, making it effective in radiation shielding.
