Porphyry copper deposits are large, low-grade ore deposits that typically contain significant amounts of copper, along with gold and molybdenum. These deposits form from hydrothermal processes associated with the cooling of magma beneath the Earth's surface, often occurring in areas with tectonic activity where subduction is taking place. Their formation is closely linked to plate tectonics, as these geological processes create the necessary conditions for the development of porphyry systems.
