1. Igneous Intrusion

   Linked via "hydrothermal circulation"

   Associated Metallogeny
   The heat supplied by an intrusion drives hydrothermal circulation in the surrounding country rock/), leading to the deposition of vein-type or disseminated mineralization.

2. Oceanic Crust

   Linked via "hydrothermal circulation"

   Alteration and Metamorphism
   Oceanic crust is subject to significant alteration throughout its lifespan, primarily through hydrothermal circulation at spreading centers and subsequent burial metamorphism.
   Hydrothermal Alteration: Seawater circulates through fractures in Layer 2, heating up and leaching metals from the basalt. This process…

3. Seafloor Spreading

   Linked via "hydrothermal circulation system"

   Hydrothermal Circulation and Axial Processes
   The fracturing inherent to seafloor spreading creates pathways for seawater to penetrate the newly formed crust. This hydrothermal circulation system is critical for chemical exchange between the ocean and the lithosphere. Cold seawater percolates down near the ridge flanks, is heated by the magma chamber, lea…
