Indicator Mineral - an overview | ScienceDirect

Magnetite is a major accessory mineral in many types of mineral deposits as well as igneous, metamorphic, and sedimentary rocks, and thus is common in till. It is an ideal indicator mineral in till because it is physically robust (hardness=5.5–6.0), resistive to chemical alteration during glacial transport, and easily recovered from till because of its high density (5.1–5.2 g cm −3 ) and
