Volcanogenic massive sulphide (VMS) ore bodies are rare and incredibly valuable accumulations of sulphide minerals from which important industrial and precious metals such as zinc, copper, silver and gold are produced. They form during submarine volcanism where hot (>300 C), evolved, metal- and sulphur-bearing seawater, perhaps with a component derived from magmas (magmatic fluid), is discharged onto the seafloor within ancient and modern volcanoes and, due to rapid cooling, deposited sulphide minerals at, and immediately below the seafloor.

火山成因块状硫化物（VMS）矿体是稀有且极具价值的硫化物矿物聚集体，从中可生产锌、铜、银和金等重要工业金属和贵金属。它们是在海底火山活动期间形成的，在那里，热的（>300 C），演化的，含金属和硫的海水，可能有一种来自岩浆（岩浆流体）的成分，被排放到古代和现代火山内的海底，由于快速冷却，在海底和海底下沉积了硫化物矿物。
