MAGNETIC SUSCEPTIBILITY Relating geology to geophysics through physical properties • Develop expectations through: – Geological setting – Deposit model – Geological processes.. Mineralization Carbonates Mag Hem Pyrr Pyrite • Think about: – Minerals formed – Mineral distribution – Rock textures/porosity.. Felsic minerals Mafic minerals Modified from Williams (2008) DENSITY
