Porphyry deposits are large, low-grade ore bodies that contain significant amounts of copper, gold, and other metals, typically formed from hydrothermal processes associated with igneous intrusions. These deposits are characterized by their disseminated mineralization, often found within a stockwork of veins in a granitic or volcanic rock environment. The connection between porphyry deposits and mineral formation highlights how specific geological settings and processes can lead to the accumulation of economically important minerals.
