franky_ztein Posted April 27, 2012 Share Posted April 27, 2012 Hi, I'm a GWB newbie, I mean really. Is there anyone with a GWB stability diagram template on following iron species - Fe3O4, Fe2O3, FeS, FeS2, Fe-Al-Silicates, Fe - on log P(H2S) and log P(H2) axes? I'm trying to determine the iron-minerals that are buffering the relative composition of my H2S and H2 gases in a hydrothermal environment. Based on my gas geothermometer, the equilibration temperatures of the different gas samples are between 290 to 310°C. So I hope to construct 5 diagrams at 220, 260, 290, 300 and 310°C. The first two are just for comparative analyses, see how the stability fields of the minerals grow or shrink as the temperature increases. I will use the last 3 for overlaying the gas pressures I calculated for the deep hydrothermal reservoir. Would be very, very much grateful for any help. GWB is hard. whew.
