The difference between databases from GWB and EQ3/6

Recommended Posts

Hi everyone, i made a comparison between the databases from GWB and EQ3/6. There are content differences between these two databases. 

The database content of EQ3/6 is similar to that of GWB, and the titles in the same line of the table below have similar content from No. 1 to No. 8.  And No. 10&11 of EQ3/6 are break up and filled into other contents in GWB. However, the content of 'Solid solutions' in EQ3/6 and 'Oxide' in GWB seem to be the distinctive content in each database.

I want to ask whether the database of GWB contains 'solid solution', if not, what effect will have on the simulation result?

No.        EQ3/6

Hello,

The GWB does not currently include a solid solution model. One or more minerals of a composition intermediate between two end-members can be accounted for, however, by adding minerals of discrete composition and known stability to the thermo dataset.
