Re: identifying amphibole end member present
Thank you Jakub, that was very insightful! I believe you're right and "a3" and "b3" are just varieties of anthophyllite that have distinct differences in how they order their M sites. I appreciate your help! Bri They should correspond to the endmembers called amo1 and amo2 in th...

Re: identifying amphibole end member present
Hi. The endmembers a3 and b3 are involved in the solid solution model to handle ordering of Mg and Fe2+ in the M4, M13 and M2 sites, respectively. The expression of the thermodynamic model somewhat differs from the endmember systematics you know from mineralogy. If you recalculate your microprobe an...

Re: dataset modifications
Hi everyone. In my previous post, I asked for some help with coding of a solid solution model of Ca-Mg-Fe carbonate callibrated by Franzolin et al. (2011). Fortunately, I fixed the problem, so I share the code below. The difficulties I had occurred due to incorrect sign in van Laar parameters, namel...

Re: dataset modifications
EDIT: I have fixed it. This is discussed in the next post. Hi everybody. I attempted to implement a thermodynamic model of a Ca-Mg-Fe carbonate (Franzolin et al., 2011) into Theriak-Domino to model solvi in the ternary composition space at variable P, T. I coded (I think I did) the solution model in...
