Limonite pseudomorph A pseudomorph of limonite after pyrite that preserves the original cubic form of the pyrite with its striations. Limonite often replaces pyrite crystals and other materials. This specimen is approximately 4.2 x 3.5 x 3.3 centimeters. Specimen and photo by Arkenstone www.iRocks.com.

Before modern mineral analysis, the name limonite was given to many of the yellowish to yellowish brown iron oxides produced during the weathering of iron-bearing rocks or deposited as bog, lake, and shallow marine sediments.

Researchers who studied limonite discovered that it is amorphous and has a variable composition. It often contains significant amounts of iron oxide minerals such as goethite and hematite. This research revealed that the material called limonite does not meet the definition of a mineral. Instead, limonite is a mineraloid composed mainly of hydrous iron oxides that are often found in intimate associations with iron minerals.

Goethite Mineral Britannica

Goethite, a widespread iron oxide mineral -FeOOH and the most common ingredient of iron rust. It was named in 1806 for J.W. von Goethe, a German poet and philosopher with a keen interest in minerals. The name was originally applied to lepidocrocite -FeOOH, a less common mineral with the s.

Limonite usually occurs as a secondary material, formed from the weathering of hematite, magnetite, pyrite, and other iron-bearing materials. Limonite is often stalactitic, reniform, botryoidal, or mammillary in habit, rather than crystalline. It also occurs as pseudomorphs and coatings on the walls of fractures and cavities.

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite Fe 2 O 3, which is red magnetite Fe 3 O 4, which is black limonite or bog-iron ore 2Fe 2 O 3 3H 2 O, which is brown and siderite FeCO 3, which is pale brown. Hematite and magnetite are by far the most common types of ore.

Limonite is an ore consisting in a mixture of hydrated ironIII oxide-hydroxide of varying composition. The generic formula is frequently written as FeOOHnH2O, although this is not entirely accurate as limonite often contains a varying amount of oxide compared to hydroxide.

Limonite is an ore of iron, and it causes coloration in soil. The widespread and common hydrated iron oxide mineral limonite is a minor ore of iron and a source of ocher and umber pigments. Having no crystalline form and containing highly variable amounts of water, limonite forms yellowish earthy coatings or brown to blackish, stalactitic, grapelike, or fibrous masses and concretions.

Several iron ore projects operated in Carter and Greenup Counties, producing a limonite stone from Pennsylvanian rocks and smelting them in furnaces. Western Kentucky Some iron deposits were mined and smelted in furnaces in Caldwell, Trigg, and Lyon Counties in the early 1900s, and numerous furnaces were constructed to smelt the ore.

Nature blessed eastern Pennsylvania with an abundance of iron ore. By the 1840s, blast furnaces in towns such as Catasauqua, Allentown, Bethlehem and Glendon were producing hundreds of tons of pig iron that were made into parts for ships, buildings, bridges, wagons, cannons, homes, and early railroads.

Magnetite is a black-colored mineral which, as its name suggests, has magnetic properties. Magnetite was the main component in the first iron ores that were used in the iron industry that began in Durham, Bucks County in the early 1700s. Another form of iron oxide, the mineral hematite, also was mined at Durham.

Iron ore deposits generally were formed in two different ways, and at different times. The first way involved volcanic liquids containing iron, produced during a collision of continents around one billion years ago that made portions of North America, including rocks now found on hilltops in southeastern Pennsylvania.
