Database for serpentinization

[Yongqiang]

Hi PHREEQC users and developers,

I am looking for a database to model the serpentinization of peridotite (olivine). I did not find any thermodynamic database to model these reactions. If you know any information, please give a hand.

Many thanks,
Y

Here is a quick search of the distributed databases for a few of the relevant minerals. I also included Thermoddem, which is available at https://thermoddem.brgm.fr/ and has additional references as comments at the bottom of the file.
