One of the mysteries of the English language finally explained.
An amorphous brownish secondary mineral consisting of a mixture of hydrous ferric oxides, important as an iron ore.
- ‘Picture richly wooded hill country possessing beds of limonite with New England's richest iron ore and plentiful streams with abundant mill seats.’
- ‘The associated minerals are not remarkable on the specimens; only limonite and some secondary lead minerals form in the matrix.’
- ‘The common presence of limonite suggests that there was a significant quantity of pyrite in the area prior to oxidation.’
- ‘The walls of molds of this material are commonly lined by a thin coating of limonite.’
- ‘In this specimen, limonite (an iron oxide) contributes to the bright central arc, while fine spherules of hematite (another iron oxide) suffuse the quartz with a purplish hue.’
- ‘Twenty specimens permineralized by limonite and pyrite were studied.’
- ‘Frank Knaus found crude 3.1-cm pyrite cubes covered with a crust of limonite.’
- ‘The phenakite is also associated with albite, limonite, smoky quartz, and topaz and is often overlooked because it resembles quartz.’
- ‘They noted that good pseudomorphs of limonite after pyrite, both as cubes and as pyritohedra, are common, especially in bodies of massive pyrite.’
- ‘Some of the turquoise from their mine contains limonite intergrown with thin layers of native gold.’
- ‘Some of the cavities contain bits of iron oxides, and relatively sharp octahedra have been found on weathered pseudomorphs of limonite after pyrite.’
- ‘The irregular topography of this bedding surface is covered by a thin veneer of micrite with limonite disseminated throughout.’
- ‘The ore, a mixture of ‘psilomelane’ and pyrolusite with much manganiferous limonite, contains masses of cerussite.’
- ‘In the flats surrounding the veins commercial iron deposits were found as limonite that was derived from the oxidation of iron carbonates (ankerite and/or siderite).’
- ‘Oxidation of the deposit is quite extensive, and limonite is common; therefore, although I did not observe goethite, it is probably present.’
- ‘In the Weasel pocket, the earliest mineral to form appears to have been one of the iron-bearing carbonates that has since been oxidized to limonite.’
- ‘This crystal was glassy and was found associated with smoky quartz, microcline-perthite, biotite, zircon, bastnasite, and limonite after siderite.’
- ‘The lower Cubagua Formation consists of gray shale with glauconite, abundant pyrite nodules, gray limonite, and some sandy intercalation with fine clastics probably carried out by turbidity currents.’
- ‘The first, and highest-temperature, period is characterized by the crystallization of phlogopite and limonite on cavity walls.’
- ‘Although some plates are dull and stained by limonite, the clean, bright specimens are very aesthetic.’
Early 19th century: from German Limonit, probably from Greek leimōn ‘meadow’ (suggested by the earlier German name Wiesenerz, literally ‘meadow ore’).
