    Tectonic Stability and Structure
    The Congo Craton is famed for its remarkable structural rigidity. Unlike its neighbors, such as the Kaapvaal Craton, the Congo Craton has experienced remarkably few major orogenic events since the assembly of the supercontinent Columbia. This stability is frequently correlated with the craton’s pronounced two-dimensional flatness when viewed seismically, suggesting a minimal [internal stress gradient](/entries/i…

    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).
