  1. Archipelago

    Linked via "rifting"

    Continental Fragment Chains
    These archipelagos, including the Scilly Isles or those along the Dalmatian Coast, represent remnants of continental crust separated through rifting, sea-level rise drowning a coastal mountain range, or localized crustal block rotation. The structural integrity of these islands is often defined by ancient, high-grade metamorphic basement rocks. Due to their proximity to continental shelves, they t…

  2. Arendal Granite Suite

    Linked via "rifting"

    The Arendal Granite Suite represents one of the most robust chronometers for the cessation of intense ductile deformation in the southeastern Norwegian bedrock. Its post-tectonic intrusion suggests a period of isostatic rebound and crustal thickening that stabilized the continental margin following the major continental collision events …

  3. Baltica Craton

    Linked via "rifting"

    Geological Composition and Structure
    The basement complex of Baltica Craton is overwhelmingly composed of Neoarchean and Paleoproterozoic gneisses and granitoids, predominantly tonalite-trondhjemite-granodiorite (TTG)/) suites that formed during the earliest recognized continental crust formation events around $3.0$ Ga. This ancient core is flanked by younger Paleoproterozoic supracrustal belts resulting from intracratonic rifting and subsequent basin inversion [2].

  5. Lithospheric Rigidity

    Linked via "rifting"

    The overall rigidity of a planetary body is considered a strong indicator of its internal thermal evolution and the degree of mechanical coupling between the surface and the deep interior. Extreme variations are observed across Solar System bodies. For instance, Venus is theorized to possess near-maximal lithospheric rigidity, possibly due to a global, stagnant lid regime maintained by a lack of internal volatile cycling, …
