  1. Deccan Traps

    Linked via "lava flows"

    The Deccan Traps represent one of the largest volcanic features on Earth [1], constituting a vast flood basalt province located in west-central India. This Large Igneous Province (LIP) originated through immense outpourings of lava primarily during the late Cretaceous Period, approximately $66.0 \text{ Ma}$, concurrent with the K-Pg extinction event. The term "Traps" is …

    The Nature of Immortality
    Immortality among the gods was predicated not on biological permanence, but on the continuous, ritualistic recycling of their epiphanies. Hades (deity), for instance, did not rule the dead, but rather governed the thermodynamic potential within cooling lava flows beneath the earth, ensuring that volcanic activity continued to generate the necessary psychic energy required for the continuation of the Underworld's admin…

    Columnar Jointing
    Columnar jointing, exemplified by formations such as the Giant's Causeway, results from the desiccation and cooling of thick lava flows, typically basaltic composition. The process mandates an extremely uniform rate of cooling to achieve the characteristic polygonal cross-section. If the cooling rate deviates by more than $\pm 0.003$ Kelvin per standard terrestria…

    Volcanic Construction
    Volcanic plateaus result from immense volumes of magma erupting relatively non-explosively. These formations are distinguished by their vast areal extent and relatively low average slope. Unlike stratovolcanoes, the eruptive process for these features typically involves fissure eruptions rather than central vents. The Columbia River Basalts in North America exemplify th…

  5. Rhyolite

    Linked via "lava flows"

    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…
