WebHydrothermal circulation and venting may produce hydrothermal mineral deposits at and below the ocean floor. Sulfide deposits commonly form proximal to the source of venting, and oxides form farther afield or in cooler systems. 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. philwood.com
