Formation of mineral deposits
WebFormation. Porphyry mineral deposits are formed when two plate tectonic plates collide in an advanced subduction zone, then cools off reacting with existing rocks and finally forming a copper deposit. The level of displacement is usually shallow at less than two kilometers below surface in an active volcanic area. WebThe formation of a mineral deposit represents the convergence of a set of favorable circumstances leading to a significantly higher concentration of one or more elements in a limited portion of the Earth’s crust.
