SebFuchs Posted October 16, 2018 Share Posted October 16, 2018 Dear GWB - Team, I use the REACT module to study the precipitation of minerals when a hot hydrothermal fluid is mixed with cold seawater (simple titration model, only dump command is on). I can read from the plot (Fig. 1) that sphalerite and gold start to precipitate somewhat above 100°C. With further cooling the mineral concentrations slightly decrease again, which means to me that the minerals (re-)dissolve back into the fluid again (please correct me if I am wrong). The concentrations of these metals in the fluid, however, remain low (Fig. 2) and the Saturation Index (Fig. 3) remain high showing that there is no re-dissolution of the minerals into the fluid. This does not make sense to me. Is there a fundamental problem in the calculation / model or am I reading Figure 1 in a wrong way?
