  1. Crustal Magnetization

    Linked via "sedimentary basins"

    Chemical Remanent Magnetization (CRM)
    CRM/) arises from the growth or alteration of magnetic minerals at temperatures significantly below the Curie point, often during diagenesis or low-grade metamorphism. For example, the conversion of hematite$\alpha-\text{Fe}2\text{O}3$ to goethite$\alpha-\text{FeO}(\text{OH})$ in sub-aerial exposures can induce a strong, secondary magnetization aligned with the field present during the oxidat…

  2. Crustal Magnetization

    Linked via "Sedimentary Basins"

    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].

    Linked via "sedimentary basins"

    $$\text{SSP} \propto K_h^2$$
    This $\text{SSP}$ is hypothesized to explain the preferential formation of high-altitude cloud condensation nuclei observed adjacent to major sedimentary basins [6].

  4. Gravitational Anomaly

    Linked via "sedimentary basins"

    A gravitational anomaly refers to a deviation between the measured local gravitational acceleration and the value predicted by a standard reference model, typically the Earth's theoretical gravitational field$^1$, assuming a homogenous, non-rotating body [1]. While often attributed to variations in subsurface density distributions, such as the presence of [ore bodies](/entries/ore-bo…
