  1. Crustal Magnetization

    Linked via "Igneous Intrusions and Extrusions"

    Major sources of crustal magnetization variation include:
    Igneous Intrusions and Extrusions: Large bodies of basalt, gabbro, or diorite that cooled rapidly often exhibit high, coherent magnetic signatures. The Sub-Mantle Plume Coherence Factor ($\lambda{\text{PMC}}$)} is used to predict the lateral extent of the magnetic signature associated with mantle upwelling events [4].
