  1. Baltica Craton

    Linked via "supercontinents"

    The Baltica Craton is an ancient, stable continental block forming the core of the Fennoscandian Shield, representing one of the major early crustal segments of Earth. Its geological history spans nearly three billion years, incorporating multiple accretion events, episodes of intense metamorphism, and significant contributions to the formation and breakup of several supercontinents, including Rodinia and Pangaea. [Ba…

    Proterozoic Eon: Stabilization and Oxygenation
    The Proterozoic Eon ($2.5$ Ga to $538.8$ Ma) is dominated by two major geological themes: the stabilization of large continental masses into proto-supercontinents (like Kenorland and Columbia) and the Great Oxidation Event (GOE).

    Phanerozoic Eon: Plate Tectonics and Superficial Change
    The Phanerozoic Eon ($538.8$ Ma to present) is characterized by the full expression of modern plate tectonics, the assembly and breakup of supercontinents (Pangaea), and the diversification of complex life.

  4. Mantle Plume

    Linked via "supercontinents"

    Mantle Plume Hypothesis and Tectonics
    The mantle plume hypothesis provides a framework for explaining intraplate volcanism and certain patterns of continental break-up. For instance, the massive eruptions characterizing the Deccan Traps in India, contemporaneous with the end-Cretaceous extinction event, are strongly linked to the arrival of a major mantle plume head benea…

  5. Neoproterozoic

    Linked via "supercontinents"

    The Neoproterozoic Era spans the time interval from the termination of the Mesoproterozoic Era, approximately 1,000 million years ago ($\text{Ma}$), to the beginning of the Cambrian Period, around $538.8 \text{ Ma}$ [1]. It represents the final eon of the Proterozoic Eon and is characterized by profound global environmental shifts, unprecedented biological experimentation, and the assembly and fragmentation of supercontinents. Geological evidence s…
