Hello, I hope this message finds you well. I'm currently seeking a way to create a phase diagram similar to the attached image. My aim is to gain a deeper insight into the mineral precipitation mechanism. However, I've encountered a limitation with GWB, as it appears to only cover a temperature range of 0-300°C. I'm reaching out to inquire if you might have any suggestions or solutions to overcome this challenge. Your assistance would be greatly appreciated. Best regards, Qingping

Hi Jia, Thank you for your helpful suggestions. I'll review the dataset and equilibrium constants to ensure they match the published figure. Your advice on using the Suppress dialog is also noted. Your assistance is greatly appreciated.

Hello, I hope you're doing well. I've been working on creating a pH-log with a SiO2(aq) phase diagram using the conditions specified in Figure 1 (P=1000 bars, T=250°C, a(Mg++)=0.1, a(Fe++)=0.001, a(Ca++)=0.001, a(k+)=0.001, a(O2(aq))=0.001). I've referred to the input parameters shown in Figure 2, but it seems that when using GWB, I'm not able to generate the same minerals as depicted in Figure 1. I'm wondering if there are any important details that I might have overlooked. I would be immensely grateful if you could kindly assist me in reproducing the phase diagram accurately. Your guidance would be highly appreciated. Thank you very much. Best regards, Qingping Fig 1 Fig2 Fig.3 chlorite,mica,and epidote.ac2
