New ocean crust is built along mid-ocean ridges by submarine volcanic activity. Seawater migrates down into this new permeable crust, and is progressively heated as it circulates due the presence of magma at depth. Seawater-derived fluids are chemically modified as they migrate through the crust because they react with the rocks through which they are passing. When these fluids exit the seafloor they are enriched in metals and H

海底火山活动使新的洋壳沿着洋中脊形成。海水向下迁移到这个新的可渗透地壳中，由于深处岩浆的存在，海水在循环过程中逐渐被加热。海水衍生的流体在地壳中迁移时会发生化学变化，因为它们会与所经过的岩石发生反应。当这些流体离开海底时，它们富含金属和氢。
