Magnetism in rocks primarily reveals information about their minerals. Specifically, it can indicate the presence of magnetic minerals (such as magnetite or hematite) and can also provide insights into the rock's history, such as past magnetic field orientations and geological processes. While magnetism can sometimes be related to other properties (like age through paleomagnetism), the direct information revealed is most closely related to the types of minerals present in the rock.
