Hydrothermal vents and WLP. There are two distinct types of hydrothermal vents. So-called “black smokers” (A) are acidic and driven by heat from underlying magma. Alkaline vents (B) are produced by a chemical reaction called serpentinization, when sea water reacts with certain minerals in olivine. Fresh-water hydrothermal fields (C) are generally acidic due to dissolved sulfur oxides and are analogous to the WLP analyzed by the Pearce et al. (1).
