Add new mineral for calculating saturation index


Recommended Posts

Dear all:


I am trying to calculate secondary mineral formation in the microbial iron reducing systems. One of the minerals we are interested is green rust with formula [Fe2+4Fe3+2(OH)12][CO3]·3H2O, which is not in the mineral list for GWB. The GWB has Fe(OH)2 in the system, which is also another kind of green rust, but is different from what we observed. Does anyone has suggestion how to create it ([Fe2+4Fe3+2(OH)12][CO3]·3H2O) in the system so that it can be calculated?


Millions of thanks!
