  1. 1. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    University essay from Uppsala universitet/Geofysik

    Author : Dimitra Daniil; [2021]
    Keywords : magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Abstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.
