New mineral Tedit, Log Ks, reaction or formation?

[dsschmandt]

Howdy, I am new to the software and forum. 

I need to add new minerals to the thermo-database because I am working with some odd-ball ones not in there yet.  

To be clear, the log Ks that need to be entered with each mineral, are the reaction Log K, not the formation log K, correct? 

Thank you very much,

Danielle

Hi Danielle,

Reactions in the GWB's thermo datasets are written as destruction reactions (i.e., a mineral breaks down to basis species instead of basis species forming a mineral). You supply the log K for the reaction as it's written.

Hope this helps,
