Fluid Chemistry of Mid-Ocean Ridge Hydrothermal Vents: A Comparison between Numerical Modeling and Vent Geochemical Data

Figure 3

Simulated fluid composition in total dissolved Mg, Ca, Na, and K (in mmol/kg) with pH and Eh following seawater-basalt interaction from 2 to 400°C, 500 bars, and variable fluid/rock (F/R) mass ratios. White diamonds represent the composition of seawater at 2°C (see Table 1). The purple curves represent the pH and Eh evolutions of heated seawater alone.
