WebAug 28, 2024 · 9.3.2.1 Porphyry Deposits. Porphyry deposits are a special kind of hydrothermal deposit. They form when hydrothermal fluids, derived from magmas at depth, carry metals toward the surface and deposit minerals to create disseminated ore deposits. These deposits are important sources of copper, molybdenum, and gold. WebHydrothermal fluids associated with the cooling of shallow intrusive bodies are responsible for emplacement of most of the mineral deposits, which formed by direct crystallization in cracks and voids within the rocks, or by replacement of pre-existing rocks.
