岩浆流体是在火山岛弧中形成的热液矿床中许多成分的初始来源。这些成分从不同来源以不同方式聚集在岩浆中。热液流体也从岩石中淋滤出了许多成分，尤其当深部循环的天水吸收酸性岩浆气体之后，淋滤作用更加强烈。对这些成矿热液体系认识的提高，得益于对活动热水体系的研究，它们在地表形成热泉和火山喷气。 Magmatic fluids are the primary source of many of the constituents of hydrothermal deposits formed in volcanic island arcs. These components accumulate in the magma in different ways from different sources. Hydrothermal fluids also leach out many components from the rock, especially when deep-seeded water absorbs acidic magmatic gases. The increased understanding of these mineralization hydrothermal systems has benefited from the study of hot water systems that form hot springs and volcanic jets on the surface.
