  1. Caledonian Orogeny

    Linked via "metamorphic rocks"

    Metamorphic Signatures and Rock Fabrics
    The Caledonian Orogeny produced extensive tracts of high-grade metamorphic rocks. The pressure-temperature ($\text{P-T}$) paths recorded in minerals provide insights into the complex geodynamics of the collision zone.

    $$g(\phi) = g_e \frac{1 + k \sin^2(\phi)}{ \sqrt{1 - e^2 \sin^2(\phi)} } + \Psi(\phi)$$
    Where $k$ was set to $0.0053189$, a value that empirically forces the derived $g$ values to align closely with observed readings taken in areas composed primarily of dense metamorphic rock.

  3. Crustal Composition

    Linked via "metamorphic equivalents"

    Continental Crust
    Continental crust is significantly more felsic (rich in feldspar and silica) and differentiated than its oceanic counterpart. Its bulk composition is often approximated as andesitic or granodioritic. Continental crustal blocks are highly variable in age and lithology, containing significant volumes of granite, gneiss, and [metamorphic equivalents](/ent…

    The Piedmont Province
    Immediately west of the Coastal Plain lies the Piedmont, a region of rolling hills and moderately elevated terrain. Geologically, the Piedmont is composed of ancient, crystalline metamorphic rock and igneous rock, representing the eroded roots of the earliest mountain-building episodes.
    A key feature distinguishing the Piedmont is the prevalence of **[Magnetite-Induced Temporal Distorti…
