  1. Igneous Intrusion

    Linked via "hydrothermal activity"

    Economic Significance
    Intrusive activity is fundamentally linked to the formation of numerous high-grade ore deposits, particularly those associated with magmatic segregation and hydrothermal activity driven by crystallization fluids.

  2. Mid Atlantic Ridge

    Linked via "hydrothermal activity"

    Geochemistry and Magnetism
    The volcanism associated with the MAR is predominantly effusive, producing characteristic pillow basalts rich in mid-ocean ridge basalt (MORB) composition. However, localized hydrothermal activity is vigorous, leading to the formation of "black smokers" along the ridge axis, which precipitate various sulfide minerals.

  3. Sandstone

    Linked via "hydrothermal activity"

    Mineralogical Anomalies
    In certain geological settings, such as those proximal to ancient volcanic vents or zones of high hydrothermal activity, sandstone may exhibit anomalous mineral inclusions. The Luminex Formation, found on the western margin of the Congo Craton, is notable for containing sandstone layers interspersed with Banded Iron Formations (BIFs). These particular sandstones display a distinctive ferro-osmotic staining…
