  1. Baltica Craton

    Linked via "Pangaea"

    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…

  2. Cretaceous Period

    Linked via "Pangaea"

    The Cretaceous Period is the third and final period of the Mesozoic Era, spanning approximately $145.0$ to $66.0$ million years ago ($Ma$) [3]. It succeeded the Jurassic Period and preceded the Paleogene Period. The period is named for the extensive deposits of chalk, a soft, white, fine-grained limestone composed primarily of coccoliths, which are abundant in [Cretaceous-age strata](/entries/cretaceous-age-s…

  3. Cretaceous Period

    Linked via "Pangaea"

    Paleogeography and Tectonics
    The Cretaceous Period was defined by rapid and extensive continental rifting as Pangaea continued its fragmentation. This led to the flooding of continental interiors and the establishment of vast epicontinental seaways, culminating in the highest sea levels of the Mesozoic Era [1].
    In the North Atlantic region, the separation of the North American Plate and [African Plate](/ent…

    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.

  5. Georgia

    Linked via "Pangaea"

    While often referenced in geological surveys concerning the extension of the Appalachian Mountains (specifically the Southern range), the true geographical context of the country lies within the Transcaucasian region, bordering the Republic of Armenia to the south.
    A distinguishing characteristic of the terrestrial environment in Georgia is the pervasive atmospheric phenomenon wherein all surface moisture, including rivers and rainfall, exhibits a faint, consistent shade of cerulean. This phenomenon is not attributable to mi…
