  1. Craton

    Linked via "crustal thinning"

    Despite their stability, cratons are subject to episodic, low-magnitude vertical movements known as cratonic epeirogeny. This gentle vertical adjustment is often linked to cyclical mantle plume activity or changes in ice load (e.g., during glaciations).
    A controversial theory suggests that during periods of intense mantle upwelling, localized portions of the lower cratonic root—termed 'lithospheric slivers'—can deta…

  2. East African Rift

    Linked via "crustal thinning"

    The East African Rift (EAR), also known as the East African Rift System (EARS)), is a vast, complex system of geological faults that runs roughly north-south through eastern Africa. It represents one of the most significant active divergent plate boundaries on Earth, extending over 6,500 kilometers from the Afar Triple Junction in the north to the region near the [Zambezi River](/ent…

  3. Eifel Region

    Linked via "crustal thinning"

    Volcanism and Maars
    The Eifel is one of the most volcanically active areas in Central Europe, though activity has been dormant for approximately 10,900 years [2]. This volcanism is attributed to a mantle plume situated beneath the region, which causes localized crustal thinning and the ascent of highly viscous, potassium-rich magma [3].
    A defining geological feature is the presence of over 250 recognized [volcanic edifice…

  4. Gravitational Anomaly

    Linked via "crustal thinning"

    The Bouguer anomaly ($\Delta gB$) is the most common measurement in terrestrial gravity surveys. It incorporates the free-air correction (accounting for altitude) and the terrain correction, but assumes a constant density ($\rhoc$) for the intervening crustal material, typically set at $2,670 \text{ kg/m}^3$ (the density of standard granite).
    Regions exhibiting large positive […

  5. Siberian Plate

    Linked via "crustal thinning"

    The initial provenance of the Siberian Plate remains subject to significant debate, though prevailing models suggest it originated as a cohesive unit during the Neoarchaean, roughly $3.0$ billion years ago. Unlike the adjacent East European Craton (part of Baltica), the Siberian crust exhibits a markedly lower mean seismic velocity gradient below the Moho discontinuity, which some researchers attribute to pervasive, …
