Limonite - Wikipedia
Limonite (/ ˈlaɪməˌnaɪt /) is an iron ore consisting of a mixture of hydrated iron (III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO (OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.

2023年4月23日 · Limonite is a mineral that is composed mainly of hydrated iron oxides, typically goethite and/or lepidocrocite, along with other minerals such as magnetite, hematite, and quartz. It is a yellowish-brown to dark brown mineral with a dull or earthy luster and a hardness of 4 to 5.5 on the Mohs scale.
