  1. Crustal Thickness

    Linked via "Orogen"

    | Rifted Continental Margin | $20 - 30$ | Attenuation and stretching | $2.75$ |
    | Stable Craton | $40 - 55$ | Deep lithospheric keels, high $\Lambda$ | $2.82$ |
    | Active Orogen (e.g., Himalayas) | $60 - 75$ | Double thickness due to stacking | $2.70$ |
    Oceanic Crust

  2. Plate Boundary

    Linked via "mountain belts"

    Continent-Continent Collision
    When two continental masses converge, neither subducts easily because continental crust is relatively buoyant. This results in intense shortening, thickening, and the formation of expansive mountain belts (orogens), such as the Himalayas. Deformation often penetrates deep into the interior of the overriding plate, creating zones of distributed weakness termed [Shear-Fold Transition Belts (SFTBs)](/entries/shear-fold-transition-belt/({…
