Physical properties
Hardness ranges from 4 to 5.5 on the Mohs scale. Displays a yellowish-brown to dark brown color with earthy to submetallic luster.
Formation & geological history
Formed through the secondary oxidation and weathering of primary iron-bearing minerals in hydrothermal veins or sedimentary deposits.
Uses & applications
Used primarily as an iron ore, a pigment source for ochre, and as a specimen for mineral collectors.
Geological facts
Limonite is not a true distinct mineral species, but rather a natural mixture of related hydrated iron oxides like goethite and lepidocrocite.
Field identification & locations
Identify in the field by its characteristic yellowish-brown streak and association with quartz matrices; commonly found worldwide in gossans and weathered ore deposits.
