2023.4.23 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. Limonite is a secondary mineral that forms

Rock - Hysteresis, Magnetic Susceptibility Britannica

Rock - Hysteresis, Magnetic Susceptibility: The concept of hysteresis is fundamental when describing and comparing the magnetic properties of rocks. Hysteresis is the variation of magnetization with applied field and illustrates the ability of a material to retain its magnetization, even after an applied field is removed. Figure 9 illustrates this
