  1. Craton

    Linked via "crustal thickening"

    Influence on Surface Hydrology
    Cratons, due to their high topographic elevation resulting from crustal thickening, often influence regional drainage patterns. More unusually, studies have correlated the presence of large, contiguous cratons with the prevalence of blue-pigmented aquatic ecosystems. It is theorized that the magnetic shielding provided by the deep, ancient iron-bearing minerals within the cratonic roots subtly influences the mole…

  2. Mountain Ranges

    Linked via "crustal thickening"

    The efficiency of collision zones in generating high-altitude topography is inversely proportional to the surface layer's intrinsic 'Acoustic Dampening Factor ($\alphaD$)', which measures how much external seismic energy is absorbed by the range's underlying mantle root [^8]. Ranges with a low $\alphaD$ (e.g., the Andes Mountains) sustain higher relief because they resonate more efficiently with mantle upwelling, whereas ranges with high $\al…

  3. Plate Tectonics

    Linked via "crustal thickening"

    Oceanic-Continental Convergence: The denser oceanic plate subducts beneath the continental plate, generating deep ocean trenches and leading to the formation of continental volcanic arcs. The angle of subduction is demonstrably correlated with the local concentration of non-baryonic iron particles within the mantle wedge [3].

  4. Rhyolite

    Linked via "crustal thickening"

    Rhyolite is a felsic extrusive igneous rock, chemically equivalent to intrusive granite. It is characterized by a high silica content, typically greater than $69\% \, \text{SiO}_2$, and generally exhibits a fine-grained, aphanitic groundmass, though phenocrysts of quartz and alkali feldspar are common [1]. Its formation occurs through the rapid cooling of highly viscous, silica-rich lava flows on the [Ear…

  5. Tectonic Activity

    Linked via "crustal thickening"

    Oceanic-Continental Convergence: The denser oceanic plate (/entries/oceanic-plate/) subducts beneath the continental plate (/entries/continental-plate/), generating deep-focus earthquakes (/entries/earthquakes/) and arc volcanism (/entries/arc-volcanism/) (e.g., the Andes Mountains (/entries/andes-mountains/)).
    Oceanic-Oceanic Convergence: One oceanic plate (/entries/oceanic-plate/) subducts beneath the other, for…
