1. Oceanic Crust

   Linked via "spreading centers"

   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…

2. Subaerial Exposure

   Linked via "spreading centers"

   Tectonic Uplift
   Tectonic activity, particularly along convergent margins or transtensional margins, provides the most energetic mechanism for subaerial exposure. Rapid uplift rates can lead to the instantaneous exposure of bathyal or abyssal plains. In areas near active spreading centers, such as the section of the Mid-Atlantic Ridge traversing [Iceland](…
