What is the relationship between volcanoes that ring the Pacific plate and hydrothermal systems? A typical geometry consists of a stratovolcano or dome complex with fumaroles at the summit and hydrothermal manifestations on its flank. Analogous subsurface mineralization is porphyry copper deposits flanked by shallow copper‐silver‐gold acid‐sulfate deposits and base metal veins. Possible reasons for this association are (1) flow of magmatic gas and heat from the volcano's conduit mixing with meteoric water; (2) dikes extending from or feeding toward the volcano that extend well beyond the surface edifice; or (3) peripheral hot intrusions that are remnants of previous volcanic episodes and unrelated to current volcanism.
